SubjectRe: [PATCH] gpio: drop unnecessary includes from include/linux/gpio/driver.h
Hi Masahiro,

[auto build test ERROR on next-20170705]
[cannot apply to gpio/for-next tegra/for-next xlnx/master v4.12 v4.12-rc7 v4.12-rc6 v4.12]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Masahiro-Yamada/gpio-drop-unnecessary-includes-from-include-linux-gpio-driver-h/20170706-123711
config: xtensa-allyesconfig (attached as .config)
compiler: xtensa-linux-gcc (GCC) 4.9.0
reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=xtensa
