Yes, there a couple of such BE/FE inversions in comments, likely 
copy/paste and typos. I just saw some earlier this week in the trigger 
error messages, e.g.

	err = dpcm_be_dai_trigger(fe, stream, SNDRV_PCM_TRIGGER_STOP);
	if (err < 0)
		dev_err(fe->dev,"ASoC: trigger FE failed %d\n", err);


We should really look for all comments with 'FE' or 'BE' and clean this up.
