Good question! Last year it was _not_ drivers/serial...

So let's ask the experts: what will be the preferred serial driver framework
in 2012?

The tty_port code should now handle all the nasty horrible
open/close/hangup logic for you. The serial midlayer uses that and is
gradually shrinking into a buffering/locking helper. The goal was to
*not* create yet another mid layer but to provide helpers that mid
layer and driver code alike can use sensibly.

So either ought to work out.
