Hi Mason,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on spi/for-next]
[also build test WARNING on v5.4-rc7]
[cannot apply to next-20191115]
[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]
