Hi Hui, Thank you for the patch! Yet something to improve: [auto build test ERROR on gpio/for-next] [cannot apply to v5.3 next-20190925] [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/Hui-Song/gpio-mpc8xxx-change-irq-handler-from-chained-to-normal/20190927-113256 base: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git for-next config: i386-allyesconfig (attached as .config) compiler: gcc-7 (Debian 7.4.0-13) 7.4.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All error/warnings (new ones prefixed by >>): In file included from include/linux/kernel.h:12:0, from drivers/gpio/gpio-mpc8xxx.c:12: drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_irq_cascade': >> include/linux/bitops.h:22:30: error: passing argument 1 of 'find_first_bit' from incompatible pointer type [-Werror=incompatible-pointer-types] for ((bit) = find_first_bit((addr), (size));
