Merge tag 'drm-fixes-for-v4.12-rc1' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "AMD, nouveau, one i915, and one EDID fix for v4.12-rc1

  Some fixes that it would be good to have in rc1. It contains the i915
  quiet fix that you reported.

  It also has an amdgpu fixes pull, with lots of ongoing work on Vega10
  which is new in this kernel and is preliminary support so may have a
  fair bit of movement.

  Otherwise a few non-Vega10 AMD fixes, one EDID fix and some nouveau
  regression fixers"
