Hi Michael,

I love your patch! Perhaps something to improve:

[auto build test WARNING on next-20200604]
[cannot apply to gpio/for-next hwmon/hwmon-next ljones-mfd/for-mfd-next shawnguo/for-next 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]
