Subject: Re: [PATCH v2 1/5] Documentation: DT: Renamed of-serial.txt to
 8250.txt

[adding Arnd to Cc, as this was his suggestion]

This makes sense to me, so:

Acked-by: Mark Rutland <mark.rutland@....com>

In future please use git format-patch -C -M when moving things around.
It should detect that this is a rename and generate a trivial diff,
rather than featuring every line of the file twice.

Thanks,
Mark.
