* toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()Dan Carpenter2014-09-031-6/+12
| | | | | | | | | | | | | | | | | | 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().

* ideapad-laptop: Constify DMI table for real!Mathias Krause2014-09-021-2/+2
| | | | | | | | | | | | | | | | This is a follow-up patch to commit 49458e83082d ("ideapad-laptop: Constify DMI table and other r/o variables") to do what its commit message says. The actual commit differs from the patch posted at https://www.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05340.html significantly, probably due to a bad merge conflict resolution. Fix up the mess and constify the DMI table for real and fix the bogus double-const of ideapad_rfk_data[].

* Revert "ideapad-laptop: Disable touchpad interface on Yoga models"Hans de Goede2014-08-281-27/+0
| | | | | | | | | | | | | | | | | | | | 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.

* ideapad-laptop: Change Lenovo Yoga 2 series rfkill handlingHans de Goede2014-08-161-14/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems that the same problems which lead to adding an rfkill blacklist and putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13 and Lenovo Yoga 2 Pro too: https://bugzilla.redhat.com/show_bug.cgi?id=1021036 https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612 Testing has shown that the firmware rfkill settings are persistent over reboots. So blacklisting the driver is not good enough, if the wifi is blocked at the firmware level the wifi needs to be explictly unblocked through the ideapad-laptop interface. And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices with hardware kill switch reports the hardware switch state, needs to be explictly set to 1 (radio enabled / not blocked). So this patch does 3 things to get proper rfkill handling on these models: 1) Instead of blacklisting the rfkill functionality, which means that people with a firmware blocked wifi get stuck in that situation, ignore the value reported by the not present hardware rfkill switch, as this is what is causing ideapad-laptop to wrongly report all radios as hardware blocks. But do register the rfkill interfaces so that the user can soft [un]block them. 2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1 3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2 series is affected.

* thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540Hans de Goede2014-06-101-1/+3
| | | | | | | | | | | | | | The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12 keys should be mapped to: control-panel, search, show-all-windows and Computer. These keys generate the sofar unused 28 - 31 hotkey scancodes. For the first 2 this nicely matches the icons on the keys, for the latter 2 the icons are somewhat creative, which is why I ended up looking them up in the user manual.

* ideapad_laptop: Introduce the use of the managed version of kzallocHimangi Saraogi2014-06-101-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. The label sysfs_failed is removed as it is no longer required. Also, linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
