In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Don't leak some plane state
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.
