   Iterate over <em class="parameter"><code>class</code></em>'s list of devices, and call <em class="parameter"><code>fn</code></em> for each,
   passing it <em class="parameter"><code>data</code></em>.  If <em class="parameter"><code>start</code></em> is set, the list iteration will start
   there, otherwise if it is NULL, the iteration starts at the
   beginning of the list.
   </p><p>

   We check the return of <em class="parameter"><code>fn</code></em> each time. If it returns anything
   other than 0, we break out and return that value.
   </p><p>

   <em class="parameter"><code>fn</code></em> is allowed to do anything including calling back into class
   code.  There's no locking restriction.
