Subject: [PATCH 13/25] powerpc: Remove useless volatiles in udbg_16550.c

From: Benjamin Herrenschmidt <[email-masked]>
Date: Thu, 06 Dec 2007 19:00:11 +1100

This removes "volatile" from the MMIO pointer udbg_comport
in udbg_16550.c driver, it's useless and makes checkpatch.pl
complain when adding things to this file.
