SubjectRe: [PATCH v3 02/11] drm: Rename plane atomic_check state names
Date


Am 19.02.21 um 13:00 schrieb Maxime Ripard:
> Most drivers call the argument to the plane atomic_check hook simply
> state, which is going to conflict with the global atomic state in a
> later rework. Let's rename it to new_plane_state (or new_state depending
> on the convention used in the driver).
