Does this go through the powerpc or the tty tree?
I'd be happy if either Ben or Greg could pick this up.

I'm happy to keep maintaining the driver itself but it
would be nice to know a definite subsystem maintainer
responsible for it.

Greg, if you want to take patches for of_serial.c generally,
I'll start forwarding them to you as they come in and make
sure they apply to your tree.
