Pull drm fixes from Dave Airlie:
 "This week's collection is pretty spread out, accel/qaic has a bunch of
  fixes, amdgpu, then lots of single fixes across a bunch of places.

  core:
   - fix drmm_mutex_init lock class

  mgag200:
   - fix gamma lut initialisation

  pl111:
   - fix FB depth on IMPD-1 framebuffer

  amdgpu:
   - Fix missing BO unlocking in KIQ error path
   - Avoid spurious secure display error messages
   - SMU13 fix
   - Fix an OD regression
   - GPU reset display IRQ warning fix
   - MST fix

  radeon:
   - Fix a DP regression

  i915:
   - PIPEDMC disabling fix for bigjoiner config

  panel:
   - fix aya neo air plus quirk

  sched:
   - remove redundant NULL check

  qaic:
   - fix NNC message corruption
   - Grab ch_lock during QAIC_ATTACH_SLICE_BO
   - Flush the transfer list again
   - Validate if BO is sliced before slicing
   - Validate user data before grabbing any lock
   - initialize ret variable to 0
   - silence some uninitialized variable warnings"
