Thanks Arnd, do you mind sharing your config?

We noticed last week that
there's a depend/select confusion might be simpler to fix, see
https://github.com/thesofproject/linux/pull/2047/commits
If I look at the first line I see a IMX_DSP=n which looks exactly like
what we wanted to fix.
Yes, I think that fix addresses the build warning as well, but looking
more closely I don't think it's what you want: If you do this on
a config that has the IMX_DSP disabled, it would appear to the
user that you have enabled the drivers, but the actual code is still
disabled.
