Merge tag 'platform-drivers-x86-v4.7-2' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86

Pull x86 platform driver fixes from Darren Hart:
 "Minor kconfig dependency cleanup, trivial mic mute hotkey for ideapad,
  and a needed improvement in adaptive keyboard detection for thinkpad:

  platform/x86:
   - Drop duplicate dependencies on X86

  thinkpad_acpi:
   - Add support for HKEY version 0x200

  ideapad_laptop:
   - Add an event for mic mute hotkey"
