[PATCH 04/11] drm/ingenic: Move no_vblank to private state

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This information is carried from the ".atomic_check" to the
".atomic_commit_tail"; as such it is state-specific, and should be moved
to the private state structure.
