These kinds of cleanup are in later patches in the series --
this one is kept strictly to the purely-mechanical sed change,
as otherwise it would be a bit awkward to review I thought.

I agree that's probably a good change to make, but it's also
a behavioural change (we would go from only creating serial
devices where -serial args are given, to always creating
them). I wanted to generally avoid having any behavioural
changes in this series.

It's a bit weird, but I don't think it's specifically wrong.

Hazard of pure-mechanical-change cleanup is that it
doesn't include coding-style fixes, but it's no
worse than it was before.
