Pull drm fixes from Dave Airlie:
 "Weekly fixes. xe and msm are the major groups, with
  amdgpu/i915/nouveau having smaller bits. xe has a bunch of hw
  workaround fixes that were found to be missing, so that is why there
  are a bunch of scattered fixes, and one larger one. But overall size
  doesn't look too out of the ordinary.

  msm:
   - virtual plane fixes:
      - drop yuv on hw where not supported
      - csc vs yuv format fix
      - rotation fix
   - fix fb cleanup on close
   - reset phy before link training
   - fix visual corruption at 4K
   - fix NULL ptr crash on hotplug
   - simplify debug macros
   - sc7180 fix
   - adreno firmware name error path fix

  amdgpu:
   - GFX10 firmware loading fix
   - SDMA 5.2 fix
   - Debugfs parameter validation fix
   - eGPU hotplug fix

  i915:
   - fix HDCP timeouts

  nouveau:
   - fix SG_DEBUG crash

  xe:
   - Fix OA format masks which were breaking build with gcc-5
   - Fix opregion leak (Lucas)
   - Fix OA sysfs entry (Ashutosh)
   - Fix VM dma-resv lock (Brost)
   - Fix tile fini sequence (Brost)
   - Prevent UAF around preempt fence (Auld)
   - Fix DGFX display suspend/resume (Maarten)
   - Many Xe/Xe2 critical workarounds (Auld, Ngai-Mint, Bommu, Tejas, Daniele)
   - Fix devm/drmm issues (Daniele)
   - Fix missing workqueue destroy in xe_gt_pagefault (Stuart)
   - Drop HW fence pointer to HW fence ctx (Brost)
   - Free job before xe_exec_queue_put (Brost)"
