Well it's not yet on dri-devel, but our pre-merge CI bots can't read such
instructions. They expect a clean new series that applies cleanly, as a
top-post, when resending stuff.

Anyway, applied.

Thanks, Daniel

Yes I know, the kernel is absolutely terrible with minor differences in
process between subsystems. And then getting sternly reprimanded if you
don't know them all :-(

Unfortunately our CI has the same problem, it can't parse all the
different flavours of how people re-submit patches, so we just had to
standardize on something.
