Merge tag 'drm-next-2022-01-21' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Thanks to Daniel for taking care of things while I was out, just a set
  of merge window fixes that came in this week, two i915 display fixes
  and a bunch of misc amdgpu, along with a radeon regression fix.

  amdgpu:
   - SR-IOV fix
   - VCN harvest fix
   - Suspend/resume fixes
   - Tahiti fix
   - Enable GPU recovery on yellow carp

  radeon:
   - Fix error handling regression in radeon_driver_open_kms

  i915:
   - Update EHL display voltage swing table
   - Fix programming the ADL-P display TC voltage swing"
