This can be even outside the loop and immediately return 0, as the
remaining part is also the loop of codec_list.

  	int err, ret = 0;
  
 +	if (list_empty(&i2sdev->sound.codec_list))
 +		return 0;
 +
  	list_for_each_entry(i2sdev, &control->list, item) {
  		/* reset i2s bus format etc. */
  		i2sbus_pcm_prepare_both(i2sdev);
