Dear all,
on v4.16-rc1+, sound does not work any more on my Dell XPS 13;
suspend-to-RAM hangs as well. I have bisected this problem down to
commit ca382f5b38f3; reverting this on top of Linus' latest (1e3510b2b053)
fixes these issues. A bit info on the system (from a working kernel):

Ideas on how to fix this properly?
