From d3abff4f339019cd208ebefa35ab9b7fcaad93b1 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 7 Mar 2012 13:05:00 +0300 Subject: [PATCH] tty: moxa: fix bit test in moxa_start() 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.
