Hi Tomer, I love your patch! Perhaps something to improve: [auto build test WARNING on pza/reset/next] [also build test WARNING on v5.4-rc5 next-20191025] [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/Tomer-Maimon/reset-npcm-add-NPCM-reset-driver-support/20191028-025236 base: https://git.pengutronix.de/git/pza/linux reset/next config: c6x-allyesconfig (attached as .config) compiler: c6x-elf-gcc (GCC) 7.4.0 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 GCC_VERSION=7.4.0 make.cross ARCH=c6x If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> Note: it may well be a FALSE warning.
