Merge tag 'drm-fixes-2021-10-29' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Quiet but not too quiet, I blame Halloween.

  The first set of amdgpu fixes missed last week, hence why this has a
  few more of them, it's mostly display fixes for new GPUs and some
  debugfs OOB stuff.

  The i915 patches have one to remove a tracepoint possible issue before
  it's a real problem, the others around cflush and display are cc'ed to
  stable as well.

  Otherwise it's just a few misc fixes.

  Summary:

  MAINTAINERS:
   - Fix the path pattern

  ttm:
   - Fix fence leak in ttm_transfered_destroy.

  core:
   - Add GPD Win3 rotation quirk

  i915:
   - Remove unconditional clflushes
   - Fix oops on boot due to sync state on disabled DP encoders
   - Revert backend specific data added to tracepoints
   - Remove useless and incorrect memory frequence calculation

  panel:
   - Add quirk for Aya Neo 2021

  seltest:
   - Reset property count for each drm damage selftest so full run will
     work correctly.

  amdgpu:
   - Fix two potential out of bounds writes in debugfs
   - Fix revision handling for Yellow Carp
   - Display fixes for Yellow Carp
   - Display fixes for DCN 3.1"
