Merge tag 'platform-drivers-x86-v3.20-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86

Pull platform driver update from Darren Hart:
 "This includes a significant update to the toshiba_acpi driver,
  bringing it to feature parity with the Windows driver, followed by
  some needed cleanups.

  The other changes are mostly minor updates, quirks, sparse fixes, or
  cleanups.

  Details:

   - toshiba_acpi:
       Add support for missing features from the Windows driver, bump the
       sysfs version, and clean up the driver.

   - thinkpad_acpi:
       BIOS string versions, unhandled hkey events.

   - msamsung-laptop:
       Add native backlight quirk, enable better lid handling.

   - intel_scu_ipc:
       Read resources from PCI configuration

   - other:
       Fix sparse warnings, general cleanups"
