Merge tag 'drm-fixes-for-v4.9-rc5' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "AMD, radeon, i915, imx, msm and udl fixes:

   - amdgpu/radeon have a number of power management regressions and
     fixes along with some better error checking

   - imx has a single regression fix

   - udl has a single kmalloc instead of stack for usb control msg fix

   - msm has some fixes for modesetting bugs and regressions

   - i915 has a one fix for a Sandybridge regression along with some
     others for DP audio.

  They all seem pretty okay at this stage, we've got one MST fix I know
  going through process for i915, but I expect it'll be next week"
