Pull drm fixes from Dave Airlie:
 "Relatively quiet week, usual amdgpu/i915/xe fixes along with a set of
  fixes for fbdev format info, which fix some regressions seen in with
  rc1.

  bridge:
   - fix OF-node leak
   - fix documentation

  fbdev-emulation:
   - pass correct format info to drm_helper_mode_fill_fb_struct()

  panfrost:
   - print correct RSS size

  amdgpu:
   - PSP fix
   - VRAM reservation fix
   - CSA fix
   - Process kill fix

  i915:
   - Fix the implementation of wa_18038517565 [fbc]
   - Do not trigger Frame Change events from frontbuffer flush [psr]

  xe:
   - Some more xe_migrate_access_memory fixes (Auld)
   - Defer buffer object shrinker write-backs and GPU waits (Thomas)
   - HWMON fix for clamping limits (Karthik)
   - SRIOV-PF: Set VF LMEM BAR size (Michal)"
