Merge tag 'drm-fixes-2026-01-16' of https://gitlab.freedesktop.org/drm/kernel

Pull drm fixes from Simona Vetter:
 "We've had nothing aside of a compiler noise fix until today, when the
  amd and drm-misc fixes showed up after Dave already went into weekend
  mode. So it's on me to push these out, since there's a bunch of
  important fixes in here I think that shouldn't be delayed for a week.

  Core Changes:
   - take gem lock when preallocating in gpuvm
   - add single byte read fallback to dp for broken usb-c adapters
   - remove duplicate drm_sysfb declarations

  Driver Changes:
   - i915: compiler noise fix
   - amdgpu/amdkfd: pile of fixes all over
   - vmwgfx:
      - v10 cursor regression fix
      - other fixes
   - rockchip:
      - waiting for cfgdone regression fix
      - other fixes
   - gud: fix oops on disconnect
   - simple-panel:
      - regression fix when connector is not set
      - fix for DataImage SCF0700C48GGU18
   - nouveau: cursor handling locking fix"
