* thinkpad_acpi: replace strnicmp with strncasecmpRasmus Villemoes2014-10-141-2/+2
| | | | | | | | | | | | | | | | | | The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

| | | | | | | | | | | | | | | | | | | | | | | | With the introduction of the new keyboard backlight implementation, the *_timeout_store function is broken, as it only supports the first kbd_type. This patch adapts such function for the new kbd_type, as well as converts from using sscanf to kstrtoint.

| * toshiba_acpi: Change HCI/SCI functions return code typeAzael Avalos2014-09-301-67/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the HCI/SCI read/write functions are returning the status of the ACPI call and also assigning the returned value of the HCI/SCI function, however, only the HCI/SCI status is being checked. This patch changes such functions, returning the value of the HCI/SCI function instead of the ACPI call status, eliminating one parameter, and returning something useful that indeed is being checked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The return codes are split in between HCI/SCI prefixes, but they are shared (used) by both interfaces, mixing hci_read/write calls with SCI_* return codes, and sci_read/write calls with HCI_* ones. This patch changes the prefix of the return codes definitions, dropping the HCI/SCI naming and instead replacing it with TOS (for TOShiba).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function name hci_raw was used before to reflect a raw (read/write) call to Toshiba's Hardware Configuration Interface (HCI), however, since the introduction of the System Configuration Interface (SCI), that "name" no longer applies. This patch changes the name of that function to tci_raw (for Toshiba Configuration Interface), and change the comments about it. Also, the HCI_WORDS definition was changed to TCI_RAW, to better reflect that we're no longer using pure HCI calls, but a combination of HCI and SCI, which form part of the Toshiba Configuration Interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In get_cpufv the return value of get_acpi is stored in the cpufv struct. Right before this value is checked for errors, it is and'ed with 0xff. This means c->cur can never be less than zero. Besides that, the actual error value is ignored. c->num is also and'ed with 0xff, which means we can ignore values below zero. Check the result of get_acpi() right away.

| * eeepc-laptop: make fan1_input really read-onlyFrans Klaver2014-09-191-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the instantiation of the fan1_input device attribute, NULL is passed as set function to store_sys_hwmon. The function pointer is never checked before dereferencing it. This is fine if we can guarantee that it will never be called with an invalid pointer, but we can't. If someone from user space decides to change the permissions on this attribute and write to it, kernel will crash. Introduce EEEPC_CREATE_SENSOR_ATTR_RO() to instantiate a read-only attribute, and declare fan1_input with it. This ensures store_sys_hwmon is never called with NULL parameters. If someone tries to write the attribute, the system will at least keep its sanity. This also causes EEEPC_CREATE_SENSOR_ATTR() to be only used for R/W attributes.This enables us to drop the _mode argument from the macro and use DEVICE_ATTR_RW() internally while we're at it.

| * eeepc-laptop: tell sysfs that the disp attribute is write-onlyFrans Klaver2014-09-191-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The disp attribute is write-only, but sysfs doesn't know this. Currently show_sys_acpi() is mimicking sysfs behavior, if the underlying acpi call should fail. This was introduced in 6dff29b63a5bf2eaf3 "eeepc-laptop: disp attribute should be write-only". This is not ideal; behaving like sysfs is better left to sysfs. Introduce EEEPC_CREATE_DEVICE_ATTR_WO() to instantiate a write-only attribute, and declare the disp attribute with it. Sysfs makes sure userspace can only write to disp at all times. This removes the need for mimicking the sysfs behavior in show_sys_acpi() and store_sys_acpi(), but we'll stick with -EIO, as changing sysfs return values should not be taken lightly. This change also causes EEEPC_CREATE_DEVICE_ATTR() to be used only for R/W attributes. This enables us to drop the _mode argument from the macro and use DEVICE_ATTR_RW() internally while we're at it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parse_arg() has three possible return values: -EINVAL if sscanf(), in short, fails; zero if "count" is zero; and "count" in all other cases But "count" will never be zero. See, parse_arg() is called by the various store functions. And the callchain of these functions starts with sysfs_kf_write(). And that function checks for a zero "count". So we can stop checking for a zero "count", drop the "count" argument entirely, and transform parse_arg() into a function that returns zero on success or a negative error. That, in turn, allows to make those store functions just return "count" on success. The net effect is that the code becomes a bit easier to understand. A nice side effect is that this GCC warning is silenced too: drivers/platform/x86/eeepc-laptop.c: In function ‘store_sys_acpi’: drivers/platform/x86/eeepc-laptop.c:279:10: warning: ‘value’ may be used uninitialized in this function [-Wmaybe-uninitialized] int rv, value; Which is, of course, the reason to have a look at parse_arg().

Many thanks to Thomas Gleixner for his help with this work. Second is an update of the generic PM domains code that has been in need of some care for quite a while. Unused code is being removed, DT support is being added and domains are now going to be attached to devices in bus type code in analogy with the ACPI PM domain. The majority of work here was done by Ulf Hansson who also has been the most active developer this time. Apart from this we have a traditional ACPICA update, this time to upstream version 20140828 and a few ACPI wakeup interrupts handling patches on top of the general rework mentioned above. There also are several cpufreq commits including renaming the cpufreq-cpu0 driver to cpufreq-dt, as this is what implements generic DT-based cpufreq support, and a new DT-based idle states infrastructure for cpuidle. In addition to that, the ACPI LPSS driver is updated, ACPI support for Apple machines is improved, a few bugs are fixed and a few cleanups are made all over. Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree maintained by Kevin Hilman that will be merged through the PM tree. Numbers-wise, the generic PM domains update takes the lead this time with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd place goes to the wakeup interrupts handling rework (13 commits). Specifics: - Rework the handling of wakeup IRQs by the IRQ core such that all of them will be switched over to "wakeup" mode in suspend_device_irqs() and in that mode the first interrupt will abort system suspend in progress or wake up the system if already in suspend-to-idle (or equivalent) without executing any interrupt handlers. Among other things that eliminates the wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt flag with interrupts which don't really need it and should not use it (Thomas Gleixner and Rafael Wysocki) - Switch over ACPI to handling wakeup interrupts with the help of the new mechanism introduced by the above IRQ core rework (Rafael Wysocki) - Rework the core generic PM domains code to eliminate code that's not used, add DT support and add a generic mechanism by which devices can be added to PM domains automatically during enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa). - Add debugfs-based mechanics for debugging generic PM domains (Maciej Matraszek). - ACPICA update to upstream version 20140828. Included are updates related to the SRAT and GTDT tables and the _PSx methods are in the METHOD_NAME list now (Bob Moore and Hanjun Guo). - Add _OSI("Darwin") support to the ACPI core (unfortunately, that can't really be done in a straightforward way) to prevent Thunderbolt from being turned off on Apple systems after boot (or after resume from system suspend) and rework the ACPI Smart Battery Subsystem (SBS) driver to work correctly with Apple platforms (Matthew Garrett and Andreas Noever). - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code, adding support for 133MHz I2C source clock on Intel Baytrail to it and making it avoid using UART RTS override with Auto Flow Control (Heikki Krogerus). - ACPI backlight updates removing the video_set_use_native_backlight quirk which is not necessary any more, making the code check the list of output devices returned by the _DOD method to avoid creating acpi_video interfaces that won't work and adding a quirk for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak) - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin) - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes, Sudip Mukherjee, Yijing Wang, and Zhang Rui) - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy, Rasmus Villemoes) - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U Murthy, Shilpasri G Bhat, Lucas Stach) - cpuidle support for DT-based idle states infrastructure, new ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus Villemoes) - ARM big.LITTLE cpuidle driver updates: support for DT-based initialization and Exynos5800 compatible string (Lorenzo Pieralisi, Kevin Hilman) - Rework of the test_suspend kernel command line argument and a new trace event for console resume (Srinivas Pandruvada, Todd E Brandt) - Second attempt to optimize swsusp_free() (hibernation core) to make it avoid going through all PFNs which may be way too slow on some systems (Joerg Roedel) - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide). - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman) - PM core fix related to clock management (Geert Uytterhoeven) - PM core's sysfs code cleanup (Johannes Berg)" * tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (105 commits) ACPI / fan: printk replacement PM / clk: Fix crash in clocks management code if !CONFIG_PM_RUNTIME PM / Domains: Rename cpu_data to cpuidle_data cpufreq: cpufreq-dt: fix potential double put of cpu OF node cpufreq: cpu0: rename driver and internals to 'cpufreq_dt' PM / hibernate: Iterate over set bits instead of PFNs in swsusp_free() cpufreq: ppc-corenet: remove duplicate update of cpu_data ACPI / sleep: Rework the handling of ACPI GPE wakeup from suspend-to-idle PM / sleep: Rename platform suspend/resume functions in suspend.c PM / sleep: Export dpm_suspend_late/noirq() and dpm_resume_early/noirq() ACPICA: Introduce acpi_enable_all_wakeup_gpes() ACPICA: Clear all non-wakeup GPEs in acpi_hw_enable_wakeup_gpe_block() ACPI / video: check _DOD list when creating backlight devices PM / Domains: Move dev_pm_domain_attach|detach() to pm_domain.h cpufreq: Replace strnicmp with strncasecmp cpufreq: powernv: Set the cpus to nominal frequency during reboot/kexec cpufreq: powernv: Set the pstate of the last hotplugged out cpu in policy->cpus to minimum cpufreq: Allow stop CPU callback to be used by all cpufreq drivers PM / devfreq: exynos: Enable building exynos PPMU as module PM / devfreq: Export helper functions for drivers ...

We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during eg reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes" * tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (52 commits) gpio: pch: Build context save/restore only for PM pinctrl: abx500: get rid of unused variable gpio: ks8695: fix 'else should follow close brace '}'' gpio: stmpe: add verbose debug code gpio: stmpe: fix up interrupt enable logic gpio: staticize xway_stp_init() gpio: handle also nested irqchips in the chained handler set-up gpio: set parent irq on chained handlers gpiolib: irqchip: use irq_find_mapping while removing irqchip gpio: crystalcove: support virtual GPIO pinctrl: bcm281xx: make Kconfig dependency more strict gpio: kona: enable only on BCM_MOBILE or for compile testing gpio, bcm-kona, LLVMLinux: Remove use of __initconst gpio: Fix ngpio in gpio-xilinx driver gpio: dwapb: fix pointer to integer cast gpio: xgene: Remove unneeded #ifdef CONFIG_OF guard gpio: xgene: Remove unneeded forward declation for struct xgene_gpio gpio: xgene: Fix missing spin_lock_init() gpio: ks8695: fix switch case indentation gpiolib: add irq_not_threaded flag to gpio_chip ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've received a bug report from a user that the touchpad control part of the ideapad-laptop ACPI interface does work for him on his "Lenovo Yoga 2 13", and that this patch causes a regression for him. Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own hands (loaned from a friend). It seems that this is a bit of hit and miss. Since the result of having a false positive here is worse, then the minor annoyance of a false touchpad disabled messages being shown after suspend / resume on models (or is it firmware versions?) where the interface does not work, simply revert the patch. This reverts commit f79a901331a823ae370584b15cd39dd110b95a0a.
