Hi Robert,

I love your patch! Yet something to improve:

[auto build test ERROR on ras/edac-for-next]
[also build test ERROR on linus/master v5.7-rc2 next-20200423]
[cannot apply to bp/for-next linux/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]
