Subject: [PATCH 3.12 102/181] applicom: dereferencing NULL on error path

From: Dan Carpenter <dan.carpenter@...cle.com>

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

===============

commit 8bab797c6e5724a43b7666ad70860712365cdb71 upstream.

This is a static checker fix.  The "dev" variable is always NULL after
the while statement so we would be dereferencing a NULL pointer here.
