SubjectRe: [PATCH v1 12/16] rtc: mediatek: cleanup header files to include
Hi Sean,

I love your patch! Yet something to improve:

[auto build test ERROR on abelloni/rtc-next]
[also build test ERROR on v4.16-rc6]
[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/sean-wang-mediatek-com/Add-support-to-MT6323-RTC-and-its-power-device/20180325-104529
base: https://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux.git rtc-next
config: tile-allmodconfig (attached as .config)
compiler: tilegx-linux-gcc (GCC) 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=tile

All errors (new ones prefixed by >>):

drivers//rtc/rtc-mt6397.c: In function 'mtk_rtc_probe':
>> drivers//rtc/rtc-mt6397.c:270:13: error: implicit declaration of function 'irq_create_mapping'; did you mean 'page_mapping'? [-Werror=implicit-function-declaration]
rtc->irq = irq_create_mapping(mt6397_chip->irq_domain, res->start);
^~~~~~~~~~~~~~~~~~
