serial_txx9: Use UPF_FIXED_PORT
The UPF_FIXED_PORT flags was introduced in 2.6.22 and it can be used instead of the driver specific verify_port routine. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
