USB: cp210x: do not map baud rates to B0
commit be125d9c8d59560e7cc2d6e2b65c8fd233498ab7 upstream. We do not implement B0 hangup yet so map low baudrates to 300bps. Signed-off-by: Johan Hovold <jhovold@gmail.com> Cc: Preston Fick <preston.fick@silabs.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
