Yes, I think so.

I always get confused when a git-tree-owner says "acked-by" against a patch
which falls within his tree's area.  An acked-by would mean "I'm OK with
the patch, please apply it".  But I'd have expected to see a "thanks,
applied" instead.

If it was "Andrew: please merge and send to Linus because it's urgent and I
can't be bothered setting up a git pull for it" then fine, but please be
explicit about that.
