11   Creates an Codec97 component.  An struct snd_ac97 instance is newly
12   allocated and initialized from the template.  The codec
13   is then initialized by the standard procedure.
14   </p><p>
15
16   The template must include the codec number (num) and address (addr),
17   and the private data (private_data).
18   </p><p>
19
20   The ac97 instance is registered as a low-level device, so you don't
21   have to release it manually.
