Re: [PATCH 4/7] kgdboc: Add earlycon_kgdboc to support early kgdb using boot consoles

[kbuild test robot]

Hi Douglas,

I love your patch! Yet something to improve:

[auto build test ERROR on arm64/for-next/core]
[also build test ERROR on tty/tty-testing v5.6 next-20200410]
[cannot apply to kgdb/kgdb-next]
[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]
