SubjectRe: [PATCH v3] gpio: winbond: add driver
Hi Maciej,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on gpio/for-next]
[also build test ERROR on v4.15-rc6 next-20180102]
[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/Maciej-S-Szmigiero/gpio-winbond-add-driver/20180103-011623
base: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git for-next
config: mips-allmodconfig (attached as .config)
compiler: mips-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/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=mips
