[SERIAL] Remove incorrect code from ioc4 serial driver
Serial drivers in general should not write uart_info->flags - they're private to serial_core. Serial drivers have no need to fiddle with tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags. Fix the ioc4 serial driver for both these points by simply removing the offending code. Acked-by: pfg@sgi.com Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
