SubjectRe: [PATCH] extcon: 3gpio: add driver for USB OTG port controlled by 3 GPIOs
Hi David,

[auto build test ERROR on chanwoo-extcon/extcon-next]
[also build test ERROR on v4.9 next-20161216]
[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/Hans-de-Goede/extcon-3gpio-add-driver-for-USB-OTG-port-controlled-by-3-GPIOs/20161219-082834
base: https://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon.git extcon-next
config: blackfin-allmodconfig (attached as .config)
compiler: bfin-uclinux-gcc (GCC) 6.2.0
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=blackfin
