is showing up in linux-next build failures for mips, parisc and s390.

sound/soc/codecs/cs4349.c:300:2: error: implicit declaration of function

Here are a few examples:

I'm guessing it needs some tighter Kconfig dependencies to block it
from being selected on arch that don't have/enable gpio stuff.
