------------------------------------------------------
Subject: serial: Fix up offenders peering at baud bits directly
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>

Stop some other people peering into the baud bits on their own and make
them use the tty_get_baud_rate() helper as a preperation for the move to
the new termios.  Corrected dependancy previous one had on new termios
structs
