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]
