[PATCH v2 0/3] drm/i915: Unpin cursor fb only after vblank.

[Maarten Lankhorst]

Fix legacy cursor updates on xe by enforcing wait between updating
registers and unpin.

In comparison with previous version, there was a small bug in the
atomic unpin path. In intel_plane_cleanup_fb we tried to deference
plane_state after calling vblank schedule. Remove plane from atomic
state immediately after scheduling to prevent this issue. It's unsafe
to deference plane_state as soon as schedule occured.

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

Ville Syrjälä (1):
  drm/i915: Use vblank worker to unpin old legacy cursor fb safely
