Merge tag 'drm-fixes-2025-02-14' of https://gitlab.freedesktop.org/drm/kernel 

Pull drm fixes from Dave Airlie:
 "Weekly drm fixes pull request, nothing too unusual, the hdmi tests
  needs a bit of refactoring after lockdep shouted at them, otherwise
  amdgpu and xe lead and a few misc otherwise.

  amdgpu:
   - Fix shutdown regression on old APUs
   - Fix compute queue hang on gfx9 APUs
   - Fix possible invalid access in PSP failure path
   - Avoid possible buffer overflow in pptable override

  amdkfd:
   - Properly free gang bo in failure path
   - GFX12 trap handler fix

  i915:
   - selftest fix: avoid using uninitialized context

  xe:
   - Remove bo->clients out of bos_lock area
   - Carve out wopcm portion from the stolen memory

  tests:
   - fix lockdep with hdmi infrastructure tests

  host1x:
   - fix uninitialised mutex usage

  panthor:
   - fix uninit variable

  hibmc:
   - fix missing Kconfig select"
