drm_plane_helper_disable is a non-atomic drivers only function, and will blow up (since no one passes the locking context it needs).
Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead.
v2: Rebase.
I've definitely never tested unload.
Looks like we could drop vc4_plane_destroy() entirely? Regardless, acked-by.
