Pull x86 platform driver updates from Matthew Garrett: "Very little of excitement here - the most significant is a new driver for detecting device freefall on Dells, other than that it's pretty much entirely minor fixes for specific machines" * 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86: hp-wmi: Enable hotkeys on some systems thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540 platform: x86: dell-smo8800: Dell Latitude freefall driver (ACPI SMO8800/SMO8810) ideapad_laptop: Introduce the use of the managed version of kzalloc platform/x86: Fix run-time dependencies of OLPC drivers platform: x86: asus-wmi.c: Cleaning up uninitialized variables ix86/mid/thermal: Introduce the use of the managed version of kzalloc platform x86 Kconfig: Refer to the laptop list in the Compal driver help Documentation: Add list of laptop models supported by the Compal driver ideapad-laptop: Blacklist rfkill control on the Lenovo Yoga 2 11 asus-wmi: Set WAPF to 4 for Asus X550CA alienware-wmi: For WMAX HDMI method, introduce a way to query HDMI cable status alienware-wmi: Update WMAX brightness method limit to 15 pvpanic: Set high notifier priority platform/x86: samsung-laptop: Add support for Samsung's NP7[34]0U3E models. toshiba_acpi: Add alternative keymap support for Satellite M840 platform-drivers-x86: intel_pmic_gpio: Fix off-by-one valid offset range check

hp-wmi: Enable hotkeys on some systems

2014-06-10T23:11:11Z

This is a third attempt to enable these buttons. The new variable being commit 997daa1bd9aca412ab97955a35b26c460c0ec7a4 (i.e. hp-wmi: detect "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query method respond with a dummy value, in this case 4. Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries. Signed-off-by: Kyle Evans Signed-off-by: Matthew Garrett

thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540

2014-06-10T23:11:10Z

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.

platform: x86: dell-smo8800: Dell Latitude freefall driver (ACPI SMO8800/SMO8810)

2014-06-10T23:11:10Z

This acpi driver provide supports for freefall sensors SMO8800/SMO8810 which can be found on Dell Latitude laptops. Driver register /dev/freefall misc device which has same interface as driver hp_accel freefall driver. So any existing applications for HP freefall sensor /dev/freefall will work for with this new driver for Dell Latitude laptops too.

ideapad_laptop: Introduce the use of the managed version of kzalloc

2014-06-10T23:11:09Z

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 Acked-by: Julia Lawall Signed-off-by: Matthew Garrett

platform/x86: Fix run-time dependencies of OLPC drivers

2014-06-10T23:11:09Z

Let the xo15-ebook driver depend on OLPC as all other OLPC drivers already do. Add COMPILE_TEST as an alternative for both xo1-rfkill and xo15-ebook, to increase the build testing coverage. Signed-off-by: Jean Delvare Cc: Matthew Garrett Signed-off-by: Matthew Garrett

platform: x86: asus-wmi.c: Cleaning up uninitialized variables

2014-06-10T23:11:08Z

There is a risk that the variable will be used without being initialized. This was largely found by using a static code analysis program called cppcheck. Signed-off-by: Rickard Strandqvist Signed-off-by: Matthew Garrett

ideapad-laptop: Blacklist rfkill control on the Lenovo Yoga 2 11

2014-06-10T23:11:06Z

The Lenovo Yoga 2 11 always reports everything as blocked, causing userspace to not even try to use the wlan / bluetooth even though they work fine. Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the rfkill initialization, it is not necessary as the priv struct is allocated with kzalloc.
