commit: cfd54d37e5cd9511b5a4a98bba6d4b2f596149cf ("[Intel-gfx] [PATCH 2/2]
drm/i915: Handle legacy cursor update as normal update")
url:
https://github.com/intel-l
From: Maarten Lankhorst
Abuse the vblank worker to make the changes as small as possible. We
need a way to sync flip_done, but if we wait on flip_done, all async
tests start failing.
Changes since v1:
- Prevent null deref when crtc is inactive.

Move hw_done to cleanup, to ensure we only unpin cursor fb after we
received a flip event. This disables the legacy_cursor_update immediate
completion of flip_done events, and waits for flip_done before cleaning
up.
