Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86
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
