Hi Linus,

It's probably a bug fix that unveils the link errors.

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: bd0b841fee49de421f615cc173ccff063303672f
commit: 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 gpio: Fix OF build problem on UM
date: 3 weeks ago
config: um-allyesconfig (attached as .config)
compiler: gcc-6 (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
git checkout 2527ecc9195e9c66252af24c4689e8a67cd4ccb9
# save the attached .config to linux build tree
make ARCH=um
