6   Scans all the CRTCs and planes in <em class="parameter"><code>dev</code></em>'s mode_config.  If they're
7   using <em class="parameter"><code>fb</code></em>, removes it, setting it to NULL. Then drops the reference to the
8   passed-in framebuffer. Might take the modeset locks.

11   Note that this function optimizes the cleanup away if the caller holds the
12   last reference to the framebuffer. It is also guaranteed to not take the
13   modeset locks in this case.
