Merge tag 'platform-drivers-x86-v4.7-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86

Pull x86 platform driver updates from Darren Hart:
 "Mostly minor updates and cleanups.  One new power management
  controller driver for Intel Core SoCs.

  platform/x86:
   - Add PMC Driver for Intel Core SoC

  dell-rbtn:
   - Ignore ACPI notifications if device is suspended

  thinkpad_acpi:
   - save kbdlight state on suspend and restore it on resume

  intel_menlow:
   - reduce code duplication

  asus-wmi:
   - provide access to ALS control

  ideapad-laptop:
   - add a new WMI string for ESC key

  surfacepro3_button:
   - Add a warning when switching to tablet mode

  sony-laptop:
   - Avoid oops on module unload for older laptops

  intel_telemetry:
   - Constify telemetry_core_ops structures

  fujitsu-laptop:
   - Use IS_ENABLED() instead of checking for built-in or module

  asus-laptop:
   - correct error handling in sysfs_acpi_set
   - remove redundant initializers
   - correct error handling in asus_read_brightness()

  fujitsu-laptop:
   - Support radio LED"
