Comment # 6 on bug 1181133 from Takashi Iwai

Thanks.

This is the new check in the DMA core side that was recently added.  That's why
it hits only on 5.10, but the culprit is rather the pwc driver that passes the
wrong device pointer, I suppose.

I'm building a test kernel with the possible fix in OBS home:tiwai:bsc1181133
repo.  The test kernel package will appear later (after an hour or so) at
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1181133/standard/

Please give it a try later.
