In soc_new_compress() when rtd->dai_link->daynmic is set, we create the pcm substreams with this call:
ret = snd_pcm_new_internal(rtd->card->snd_card, new_name, num, 1, 0, &be_pcm);
which passes 0 as capture_count leading to
be_pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream
being NULL, hence when trying to set rtd a few lines below we get an oops. Fix by removing this line of code since CAPTURE substream will always be NULL.
Why will the capture stream always be NULL? There should be no intrinsic reason why we can't have hardware support for capturing compressed audio.
