8   This function cleans up plane state, specifically framebuffers, from the old
9   configuration. Hence the old configuration must be perserved in <em class="parameter"><code>old_state</code></em> to
10   be able to call this function.
11   </p><p>
12
13   This function must also be called on the new state when the atomic update
14   fails at any point after calling <code class="function">drm_atomic_helper_prepare_planes</code>.
