   - fix regression in i915 polling
   - fix docs build warning
   - fix DG2 idle power consumption

  bridge:
   - samsung-dsim: init fix

  panfrost:
   - fix speed binning issue

  dma-buf:
   - fix recursive lock in fence signal

  vmwgfx:
   - fix shader stage validation
   - fix NULL ptr derefs in gem put"
