SubjectRe: [PATCH] gpio: Wakeup gpio controller when it is used as IRQ controller
Hi Borsodi,

[auto build test ERROR on gpio/for-next]
[also build test ERROR on v4.14-rc1 next-20170921]
[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/Michal-Simek/gpio-Wakeup-gpio-controller-when-it-is-used-as-IRQ-controller/20170922-070306
base: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git for-next
config: i386-randconfig-x000-201738 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):
