Hi Dmitry,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tty/tty-testing]
[also build test ERROR on next-20200110]
[cannot apply to linux/master usb/usb-testing linus/master v5.5-rc5]

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]
