Hi Matthew,

I love your patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on linux/master soc-thermal/next v5.7-rc1 next-20200413]
[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]
