Subject: drivers/gpio/gpiolib.c:3215: undefined reference to
`of_get_named_gpiod_flags'
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: d71f058617564750261b673ea9b3352382b9cde4
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
