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

Pull intel and dp mst drm fixes from Dave Airlie:
 "Intel had a few more fixes lined up and no point me sitting on them,
  along with a DP MST fix from Rob for a race at undock + vt switch"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm: fix fb-helper vs MST dangling connector ptrs (v2)
  drm/i915: BDW Fix Halo PCI IDs marked as ULT.
  drm/i915: Fix and clean BDW PCH identification
  drm/i915: Only fence tiled region of object.
  drm/i915: fix inconsistent brightness after resume
  drm/i915: Init PPGTT before context enable
