Merge branch 'serial'
* serial:
imx: Check for NULL pointer deref before calling tty_encode_baud_rate
atmel_serial: fix hang in set_termios when crtscts is enabled
MAINTAINERS: update 8250 section, give Alan Cox a name
tty: fix sanity check
pty: Narrow the race on ldisc locking
tty: fix unused warning when TCGETX is not defined
ldisc: debug aids
ldisc: Make sure the ldisc isn't active when we close it
tty: Fix leaks introduced by the shift to separate ldisc objects
Fix conflicts in drivers/char/pty.c due to earlier version of the ldisc
race narrowing.
