Hi Rasmus, Thank you for the patch! Yet something to improve: [auto build test ERROR on linus/master] [cannot apply to v5.3 next-20190918] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Rasmus-Villemoes/backlight-pwm_bl-fix-cie1913-comments-and-constant/20190919-225123 config: x86_64-randconfig-s0-201937 (attached as .config) compiler: gcc-5 (Ubuntu 5.5.0-12ubuntu1) 5.5.0 20171010 reproduce: # save the attached .config to linux build tree make ARCH=x86_64 :::::: branch date: 2 hours ago :::::: commit date: 2 hours ago If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All errors (new ones prefixed by >>): drivers/iio/common/hid-sensors/hid-sensor-attributes.c: In function 'simple_div': >> drivers/iio/common/hid-sensors/hid-sensor-attributes.c:94:35: error: implicit declaration of function 'int_pow' [-Werror=implicit-function-declaration] *micro_frac = (rem / divisor) * int_pow(10, 6 - exp);
