Pull drm fixes from Dave Airlie:
 "Weekly fixes round, looks like a few people woke up, got a bunch of
  fixes across the drivers. Bit bigger than I'd like but they all seem
  fine and hopefully it quiets down now.

  sun4i, kirin, mediatek and exynos on the ARM side. virtio-gpu and core
  have some mmap fixes, and there is a dma-buf leak. one ttm fence leak
  is also fixed.

  Otherwise it's mostly amdgpu and i915.

  One of the i915 fixes is for a very long latency I was seeing (using
  latencytop) running gnome-shell locally when using firefox and eating
  nearly all my RAM, it really helps with desktop responsiveness esp
  when firefox is chewing a lot.

  dma-buf:
   - fix memory leak

  core:
   - shmem object mmap fix.

  ttm:
   - Fix fence leak in ttm_buffer_object_transfer().

  amdgpu:
   - Gfx reset fix for gfx9, 10
   - Fix for gfx10
   - DP MST fix
   - DCC fix
   - Renoir power fixes
   - Navi power fix

  i915:
   - Break up long lists of object reclaim with cond_resched()
   - PSR probe fix
   - TGL workarounds
   - Selftest return value fix
   - Drop timeline mutex while waiting for retirement
   - Wait for OA configuration completion before writes to OA buffer

  virtio:
   - Fix resource id creation race in virtio.
   - mmap fixes

  sun4i:
   - Fixes for sun4i VI layer format support.

  kirin:
   - kirin: Revert "Fix for hikey620 display offset problem"

  exynos:
   - fix a kernel oops problem in case that driver is loaded as module.
   - fix a regulator warning issue when I2C DDC adapter cannot be gathered.
   - print out an error message only in error case excepting -EPROBE_DEFER.

  mediatek:
   - overlay, cursor and gce fixes"
