[0/3] drm/i915/display: Unpin cursor worker in vblank worker series.

Message

Use the vblank worker to unpin fb, for the legacy cursor fastpath and atomic cursor slowpath.
This prevents pipe fault errors from the cursor plane in Xe.

A small race appears to exist in kms_universal_plane@cursor-fb-leak on dg2, not sure why. I tried reproducing it and failed.

Maarten Lankhorst (2):
  drm: Add drm_vblank_work_flush_all().
  drm/i915: Use the same vblank worker for atomic unpin

  drm/i915: Use vblank worker to unpin old legacy cursor fb safely
