Ok, I'm alright with you queueing these if that makes it easier. Feel
free to add:

Acked-by: Olof Johansson <olof at lixom.net>

Only concern is if we cause confusion on where people should send
these patches down the road, but there aren't that many authors of
them so it's not a huge problem.

And with a maintainer on that, that'd resolve the "where do I send
this" issue. The maintainer, of course, needs to know where to feed
things next, but that's easier to solve.
