Pull drm fixes from Dave Airlie:
 "Xmas eve pull request present.

  Just some fixes that trickled in this past week: Mostly amdgpu fixes,
  with a dma-buf/mips build fix and some misc komeda fixes.

  dma-buf:
   - fix build on mips

  komeda:
   - fix commit tail operation order
   - NULL pointer fix
   - out of bounds access fix

  ttm:
   - remove an unused function

  amdgpu:
   - Vangogh SMU fixes
   - Arcturus gfx9 fixes
   - Misc display fixes
   - Sienna Cichlid SMU update
   - Fix S3 display memory leak
   - Fix regression caused by DP sub-connector support

  amdkfd:
   - Properly require pcie atomics for gfx10"
