Pull drm fixes from Dave Airlie:
 "Weekly fixes roundup, nothing two serious, some usb device regressions
  are fixed, and i915 GVT has a bigger fix but otherwise not really much
  happening here.

  core:
   - fb bpp check regression fix
   - release/unplug fix
   - use after free fixes

  i915:
   - fix mmap range checks
   - fix gvt ppgtt mm LRU list access races
   - fix selftest error pointer check
   - fix a macro definition (pre-emptive for potential further backports)
   - fix one AML SKU ULX status

  amdgpu:
   - one variable refresh rate fix

  udl:
   - fix EDID reading

  tegra:
   - build/warning fixes

  meson:
   - cleanup path fixes
   - TMDS clock filter fix

  rockchip:
   - NV12 buffers and scalar fix"
