Hi Michael,

I love your patch! Perhaps something to improve:

[auto build test WARNING on robh/for-next]
[also build test WARNING on ljones-mfd/for-mfd-next rockchip/for-next keystone/next arm64/for-next/core arm-soc/for-next shawnguo/for-next v5.7-rc1 next-20200414]
[cannot apply to xlnx/master]
[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]
