Merge tag 'drm-fixes-for-v4.7-rc4' of git://people.freedesktop.org/~airlied/linux 

Pull drm fixes from Dave Airlie:
 "The main drm fixes pull for rc4: one regression fix in the connector
  refcounting, and an MST fix.

  There rest is nouveau, amdkfd, i915, etnaviv, and radeon/amdgpu fixes,
  mostly regression or black screen fixes"
