[PATCH] serial: Fix up offenders peering at baud bits directly
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 Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
