   This function is used to free memory allocated by sparse keymap
   in an input device that was set up by <code class="function">sparse_keymap_setup</code>.
</p></div><div class="refsect1"><a id="idm140404953652432"></a><h2>NOTE</h2><p>
   It is safe to cal this function while input device is
   still registered (however the drivers should care not to try to
   use freed keymap and thus have to shut off interrups/polling
   before freeing the keymap).
