From: Greg KH
Date: Wed Feb 01 2012 - 16:23:28 EST


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

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

From: Johan Hovold <jhovold@xxxxxxxxx>

commit be125d9c8d59560e7cc2d6e2b65c8fd233498ab7 upstream.

We do not implement B0 hangup yet so map low baudrates to 300bps.
