Subject: [PATCH 15/15] msm: fixups to match current code
Date: Mon, 22 Jun 2009 18:43:18 +0100	[thread overview]
Message-ID: <20090622174316.25341.77853.stgit@t61.ukuu.org.uk> (raw)
In-Reply-To: <20090622172929.25341.31151.stgit@t61.ukuu.org.uk>

From: Alan Cox <alan@linux.intel.com>

The tty layer is now a bit more fussy about reporting the right baud rate
back. Make the msm driver match the current state of affairs.
