  dp-mst:
   - Fix DSC decompression detection

  hdmi:
   - Fix infoframe size

  sched:
   - Update maintainers
   - Fix race condition whne queueing up jobs
   - Fix locking in drm_sched_entity_modify_sched()
   - Fix pointer deref if entity queue changes

  sysfb:
   - Disable sysfb if framebuffer parent device is unknown

  amdgpu:
   - DML2 fix
   - DSC fix
   - Dispclk fix
   - eDP HDR fix
   - IPS fix
   - TBT fix

  i915:
   - One fix for bitwise and logical "and" mixup in PM code

  xe:
   - Restore pci state on resume
   - Fix locking on submission, queue and vm
   - Fix UAF on queue destruction
   - Fix resource release on freq init error path
   - Use rw_semaphore to reduce contention on ASID->VM lookup
   - Fix steering for media on Xe2_HPM
   - Tuning updates to Xe2
   - Resume TDR after GT reset to prevent jobs running forever
   - Move id allocation to avoid userspace using a guessed number to
     trigger UAF
   - Fix OA stream close preventing pbatch buffers to complete
   - Fix NPD when migrating memory on LNL
   - Fix memory leak when aborting binds

  panthor:
   - Fix locking
   - Set FOP_UNSIGNED_OFFSET in fops instance
   - Acquire lock in panthor_vm_prepare_map_op_ctx()
   - Avoid uninitialized variable in tick_ctx_cleanup()
   - Do not block scheduler queue if work is pending
