Subject: [patch] tty: moxa: fix bit test in moxa_start()
Date: Wed, 07 Mar 2012 10:05:00 +0000	[thread overview]
Message-ID: <20120307100500.GD25452@elgon.mountain> (raw)

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.
