Alan Tull reported the same problem before with a patch that needed
respinning. The issue is that we have a static soc_pcm_ops and we don't
properly indirect everything, we copy some of the ops into snd_pcm_ops
directly. This means that if those ops end up being used then they end
up being the same for both drivers.
I was actually intending to fix this over Christmas.
