Pull drm fixes from Dave Airlie:
 "As per usual xe/amdgpu are the leaders, with some i915 and then a
  bunch of scattered fixes. There are a bunch of stability fixes for
  some older amdgpu cards.

  draw:
   - Avoid color truncation

  gpuvm:
   - Avoid kernel-doc warning

  sched:
   - Avoid double free

  i915:
   - Skip GuC communication warning if reset is in progress
   - Couple frontbuffer related fixes
   - Deactivate PSR only on LNL and when selective fetch enabled

  xe:
   - Increase global invalidation timeout to handle some workloads
   - Fix NPD while evicting BOs in an array of VM binds
   - Fix resizable BAR to account for possibly needing to move BARs
     other than the LMEMBAR
   - Fix error handling in xe_migrate_init()
   - Fix atomic fault handling with mixed mappings or if the page is
     already in VRAM
   - Enable media samplers power gating for platforms before Xe2
   - Fix de-registering exec queue from GuC when unbinding
   - Ensure data migration to system if indicated by madvise with SVM
   - Fix kerneldoc for kunit change
   - Always account for cacheline alignment on migration
   - Drop bogus assertion on eviction

  amdgpu:
   - Backlight fix
   - SI fixes
   - CIK fix
   - Make CE support debug only
   - IP discovery fix
   - Ring reset fixes
   - GPUVM fault memory barrier fix
   - Drop unused structures in amdgpu_drm.h
   - JPEG debugfs fix
   - VRAM handling fixes for GPUs without VRAM
   - GC 12 MES fixes

  amdkfd:
   - MES fix

  ast:
   - Fix display output after reboot

  bridge:
   - lt9211: Fix version check

  panthor:
   - Fix MCU suspend

  qaic:
   - Init bootlog in correct order
   - Treat remaining == 0 as error in find_and_map_user_pages()
   - Lock access to DBC request queue

  rockchip:
   - vop2: Fix destination size in atomic check"
