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
