[PATCH 19/29] drm/atomic-helper: Change parameter name of drm_atomic_helper_cleanup_planes()

From: Maxime Ripard
Date: Wed Jan 15 2025 - 16:09:01 EST


drm_atomic_helper_cleanup_planes() is one of the final part of a commit,
and will free up all plane resources used in the previous commit. It
takes the drm_atomic_state being committed as a parameter.

However, that parameter name is called (and documented) as old_state,
which is pretty confusing. Let's rename that variable as state.
