[kernel test robot]

Hi Scott,

I love your patch! Yet something to improve:

[cannot apply to char-misc/char-misc-testing driver-core/driver-core-testing kselftest/next integrity/next-integrity linus/master v5.7 v5.7-rc7 v5.7-rc6 v5.7]
[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]
