Merge tag 'drm-fixes-for-4.8-rc2' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This contains a bunch of amdgpu fixes, and some i915 regression fixes.

  It also contains some fixes for an older regression with some EDID
  changes and some 6bpc panels.

  Then there are the lockdep, cirrus and rcar-du regression fixes from
  this window"
