Thanks, I'll pull this in for -fixes as far as get_maintainer.pl.. I'm not entirely sure.. we don't list linux-kernel@xxxxxxxxxxxxxxx explicitly, but neither do a lot of the other driver entries. Possibly this is a oversight in the MAINTAINERS entry? Either way, I guess I'd say that it isn't intentional.
