Pull drm fixes from Dave Airlie:
 "Was relatively quiet this week, but still a few pulls came in, pretty
  much small fixes across the board, a couple of regression fixes in the
  amdgpu/radeon code, msm has a few minor fixes across the board, a
  panel regression fix also.

  amdgpu:
   - DCN3 fix
   - Fix CAC setting regression for TOPAZ
   - Fix ttm regression

  radeon:
   - Fix ttm regression

  msm:
   - a5xx/a6xx timestamp fix
   - microcode version check
   - fail path fix
   - block programming fix
   - error removal fix

  i915:
   - Fix invalid access to ACPI _DSM objects

  xen:
   - Fix use-after-free in xen
   - minor duplicate defintion cleanup

  vc4:
   - Reduce fifo threshold on hvs4 to fix a fifo full error
   - minor redunantant assignment cleanup

  panel:
   - Disable TE support for Droid4 and N950"
