Ugh, that's unfortunate. I have a set of scripts I use to build-test
before pushing, but I don't usually do full allyesconfig builds. It
seems like pwm-lpss.c might only be missing a linux/io.h include. It
will likely be Monday before I find the time to properly test and fix
this, do you want me to remove the commits from the pwm/for-next branch
so you don't have to revert it again?
