The allocator then loops * over all plane states to compute the free planes bitmask, allocates hardware * planes based on that bitmask, and stores the result back in the plane states. * * For this to work we need to access the current state of planes not touched by * the atomic update. To ensure that it won't be modified, we need to lock all * planes using drm_atomic_get_plane_state().
