commit: 296ad4acb8efeffa456e344c73dc9459f4e9e1a0 gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
date: 6 weeks ago
config: um-allmodconfig (attached as .config)
compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
git checkout 296ad4acb8efeffa456e344c73dc9459f4e9e1a0
# save the attached .config to linux build tree
make ARCH=um
