5.4-stable review patch. If anyone has any objections, please let me know.

From: Daniel Vetter <daniel.vet...@ffwll.ch>
[ Upstream commit fd0ad3b2365c1c58aa5a761c18efc4817193beb6 ]
Apparently no one noticed that mdp5 plane states leak like a sieve
ever since we introduced plane_state->commit refcount a few years ago
in 21a01abbe32a ("drm/atomic: Fix freeing connector/plane state too
early by tracking commits, v3.")
Fix it by using the right helpers.

by tracking commits, v3.")
