Kind reminder regarding this series.
Some of the patches have received a review, others did not yet.
I'd be great to have the Ideapad with working audio without being
force to build with downstream kernel patches...

I've added Dmytro Malovanyi and Jani Nikula who have both also
recently been involved with other patches for the same driver.

If there is anything I can do from my end, please let me know.


Cheers


Daniel
