I added that to my randconfig tree now. I did a cherry-pick of that
commit, I tried a 'git merge'
first, but that pulled in a lot of other stuff that conflicts with linux-next.

Your patch does not fix the link error though, I'm fairly sure we need
my one-liner
on top still. In this case, SND_SOC_SOF=y gets selected by
SND_SOC_SOF_INTEL_COMMON=y, while SND_SOC_SOF_COMPRESS=m gets
selected by SND_SOC_SOF_IMX_COMMON=m, and then ignored because the Makefile
only cares about =y objects built into the common module.
