Merge tag 'drm-fixes-for-v4.9-rc4' of git://

Pull drm fixes from Dave Airlie:
 "Fixes for amdgpu, radeon, intel, imx and virtio-gpu.

  This is a bit larger than I'd like, but I had some stuff I meant to
  send for -rc3 but was waiting for the PAT regression fix to land. So
  this is really fixes for rc3 and rc4 in one go.

  There are a set of fixes for an oops we've been seeing around MST
  display unplug, along with more suspend/resume and shutdown fixes for
  amdgpu, one power management follow on fix for nouveau, and set of imx
  fixes, and a single virtio-gpu regression fix"
