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

Pull x86 platform driver updates from Matthew Garrett:
 "Nothing overly dramatic here - improved support for the Classmate,
  some random small fixes and a rework of backlight management to deal
  with some of the more awkward cases."

* 'linux-next' of git://cavan.codon.org.uk/platform-drivers-x86:
  thinkpad_acpi: Free hotkey_keycode_map after unregistering tpacpi_inputdev
  thinkpad_acpi: Fix a memory leak during module exit
  thinkpad_acpi: Flush the workqueue before freeing tpacpi_leds
  dell-laptop: Add 6 machines to touchpad led quirk
  ACER: Fix Smatch double-free issue
  ACER: Fix up sparse warning
  asus-nb-wmi: add some video toggle keys
  asus-nb-wmi: add wapf quirk for ASUS machines
  classmate-laptop: Fix extra keys hardware id.
  classmate-laptop: Add support for Classmate V4 accelerometer.
  asus-wmi: enable resume on lid open
  asus-wmi: control backlight power through WMI, not ACPI
  samsung-laptop: support R40/R41
  acpi/video_detect: blacklist samsung x360
  samsung-laptop: X360 ACPI backlight device is broken
  drivers-platform-x86: use acpi_video_dmi_promote_vendor()
  acpi: add a way to promote/demote vendor backlight drivers
  ACER: Add support for accelerometer sensor
  asus-wmi: use ASUS_WMI_METHODID_DSTS2 as default DSTS ID.
