Merge tag 'drm-fixes-2021-07-16' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Regular rc2 fixes though a bit more than usual at rc2 stage, people
  must have been testing early or else some fixes from last week got a
  bit laggy.

  There is one larger change in the amd fixes to amalgamate some power
  management code on the newer chips with the code from the older chips,
  it should only affects chips where support was introduced in rc1 and
  it should make future fixes easier to maintain probably a good idea to
  merge it now.

  Otherwise it's mostly fixes across the board.

  ttm:
   - Avoid NULL-ptr deref in ttm_range_man_fini()

  vmwgfx:
   - Fix a merge commit

  qxl:
   - fix a TTM regression

  amdgpu:
   - SR-IOV fixes
   - RAS fixes
   - eDP fixes
   - SMU13 code unification to facilitate fixes in the future
   - Add new renoir DID
   - Yellow Carp fixes
   - Beige Goby fixes
   - Revert a bunch of TLB fixes that caused regressions
   - Revert an LTTPR display regression

  amdkfd
