Pull drm fixes from Dave Airlie:
 "Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
  failing to load if debugfs is off in Kconfig, otherwise the i915 and
  mediatek, and amdgpu fixes all fairly normal.

  Nouveau has a couple of display fixes, but it has a fix for a
  longstanding race condition in it's memory manager code, and the fix
  mostly removes some code that wasn't working properly and has no
  userspace users. This fix makes the diffstat kinda larger but in a
  good (negative line-count) way.

  core:
   - fix drm_wait_vblank uapi copying bug

  ttm:
   - fix debugfs init when debugfs is off

  amdgpu:
   - vega10 SMU workload fix
   - DCN VM fix
   - DCN 3.01 watermark fix

  amdkfd:
   - SVM fix

  nouveau:
   - ampere display fixes
   - remove MM misfeature to fix a longstanding race condition

  i915:
   - tweaked display workaround for all PCHs
   - eDP MSO pipe sanity for ADL-P fix
   - remove unused symbol export

  mediatek:
   - AAL output size setting
   - Delete component in remove function"
