Pull drm fixes from Dave Airlie:
 "It has a few scattered msm and i915 fixes, a few core fixes and a
  mediatek feature revert.

  I've had to pick a bunch of patches into this, as the drm-misc-fixes
  tree had a bunch of vc4 patches I wasn't comfortable with sending to
  you at least as part of this, they were delayed due to your reverts.
  If it's really useful as fixes I'll do a separate pull.

  Summary:

  Core:
   - clamp fbdev size
   - edid cap blocks read to avoid out of bounds

  panel:
   - fix missing crc32 dependency

  msm:
   - Fix a new crash on dev file close if the dev file was opened when
     GPU is not loaded (such as missing fw in initrd)
   - Switch to single drm_sched_entity per priority level per drm_file
     to unbreak multi-context userspace
   - Serialize GMU access to fix GMU OOB errors
   - Various error path fixes
   - A couple integer overflow fixes
   - Fix mdp5 cursor plane WARNs

  i915:
   - Fix ACPI object leak
   - Fix context leak in user proto-context creation
   - Fix missing i915_sw_fence_fini call

  hyperv:
   - hide hw pointer

  nouveau:
   - fix engine selection bit

  r128:
   - fix UML build

  rcar-du:
   - unconncted LVDS regression fix

  mediatek:
   - revert CMDQ refinement patches"
