Re: [PATCH 1/2] video: ssd1307fb: Print PWM period using 64-bit format specifier
by kernel test robot
Hi Thierry,
I love your patch! Perhaps something to improve:
[auto build test WARNING on linus/master]
[also build test WARNING on v5.8-rc1 next-20200615]
[cannot apply to pwm/for-next]
[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]
