platform-drivers-x86 for v4.12-1

Browse Source 
This pull requests represents a significantly larger and more complex set of
 changes than those of prior merge windows. In particular, we had several changes
 with dependencies on other subsystems which we felt were best managed through
 merges of immutable branches, including one each from input, i2c, and leds. Two
 patches for the watchdog subsystem are included after discussion with Wim and
 Guenter following a collision in linux-next (this should be resolved and you
 should only see these two appear in this pull request). These are called out in
 the "External" section below.
 
 Summary of changes:
  - significant further cleanup of fujitsu-laptop and hp-wmi
  - new model support for ideapad, asus, silead, and xiaomi
  - new hotkeys for thinkpad and models using intel-vbtn
  - dell keyboard backlight improvements
  - build and dependency improvements
  - intel * ipc fixes, cleanups, and api updates
  - single isolated fixes noted below
