Hi Dmitry,

[auto build test ERROR on: gpio/for-next]
[also build test ERROR on: v4.3 next-20151105]

url:    https://github.com/0day-ci/linux/commits/Dmitry-Torokhov/gpiolib-tighten-up-ACPI-legacy-gpio-lookups/20151106-034359
base:   https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git for-next
config: mips-txx9 (attached as .config)
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=mips
