Incorrect uart_write_wakeup() calls cause reference to a NULL tty pointer. This has been fixed in the sunsab and sunzilog serial drivers in October 2005. Update the ip22zilog, which is based on sunzilog, accordingly. Signed-off-by: NMartin Michlmayr <tbm@cyrius.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk
