Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "A bunch of fixes for radeon, intel, omap and one amdkfd fix.

  Radeon fixes are all over, but it does fix some cursor corruption
  across suspend/resume.  i915 should fix the second warn you were
  seeing, so let us know if not.  omap is a bunch of small fixes"
