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
