by kbuild test robot
Hi Scott,
I love your patch! Perhaps something to improve:
[auto build test WARNING on driver-core/driver-core-testing]
[also build test WARNING on next-20200421]
[cannot apply to char-misc/char-misc-testing kselftest/next linus/master v5.7-rc2]
[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]
