As I already mentioned in the private-thread which Pierre-Louis started
with me, Jaroslav Kysela and Liam about this I would advice against applying
that series for now. First we need to put in more work to make sure that
the new drivers are actually ready.

Also I must say that I'm quite disappointed that since I, as the person
who more or less single handedly have made sure that audio works properly o
Bay Trail and Cherry Traul devices (*), has not been Cc-ed on that series,
that seems like a huge oversight.

Anyways I will reply in the thread of the series and ask Mark to revert
the entire series. Since IMHO the new drivers are clearly not ready yet.
Yesterday I ran my first set of tested and I immediately hit a DSP
hang doing just a few very basic tests.

Regards,

Hans

like moving the userspace stuff to UCM2.
