   Creates a new info entry and assigns it to the given card.
   Unlike <code class="function">snd_info_create_card_entry</code>, this function registers the
   info entry as an ALSA device component, so that it can be
   unregistered/released without explicit call.
   Also, you don't have to register this entry via <code class="function">snd_info_register</code>,
   since this will be registered by <code class="function">snd_card_register</code> automatically.
   </p><p>

   The parent is assumed as card-&gt;proc_root.
   </p><p>

   For releasing this entry, use <code class="function">snd_device_free</code> instead of
   <code class="function">snd_info_free_entry</code>. 
   </p><p>

   Returns zero if successful, or a negative error code on failure.
