From 37a6c7d0096bb54daa2cf3cc66a66bdbb57cb204 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 16 Oct 2007 01:24:02 -0700 Subject: [PATCH] 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.
