[ 030/175] tty: moxa: fix bit test in moxa_start()

[Greg KH]

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

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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 58112dfbfe02d803566a2c6c8bd97b5fa3c62cdc upstream.

This is supposed to be doing a shift before the comparison instead of
just doing a bitwise AND directly.  The current code means the start()
just returns without doing anything.
