* ideapad_laptop: Add Lenovo G40-30 to devices without radio switchPhilippe Coval2015-05-031-0/+7
| | | | | | | | | | | | | | | | | Lenovo G40-30 does not provide any physical radio switch to user. Therefore disable the rfkill switch identically to the Yoga 2 approach. (Note for later, models ids are sorted alphabetically). Benefit is to make wireless available again without unloading module. It was tested successfully on 4.1.0-rc1 base with this model: (LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).

* 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.

* 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>

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

Plus the ideapad_platform private sysfs attributes, i.e. camera_power and fan_mode, are also moved to the new platform device node. The previous platform device node "ideapad" is removed.
