Subject: [41/89] USB: ftdi_sio: fix initial baud rate
Date: Wed, 01 Feb 2012 13:00:05 -0800	[thread overview]
Message-ID: <20120201210047.519619161@clark.kroah.org> (raw)
In-Reply-To: <20120201210505.GA26028@kroah.com>

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <jhovold@gmail.com>

commit 108e02b12921078a59dcacd048079ece48a4a983 upstream.

Fix regression introduced by commit b1ffb4c851f1 ("USB: Fix Corruption
issue in USB ftdi driver ftdi_sio.c") which caused the termios settings
to no longer be initialised at open. Consequently it was no longer
possible to set the port to the default speed of 9600 baud without first
changing to another baud rate and back again.
