Subject: [65/91] isdn: gigaset: add missing unlock

2.6.34-stable review patch.  If anyone has any objections, please let us know.

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

From: Dan Carpenter <error27@...il.com>

commit 7e27a0aeb98d53539bdc38384eee899d6db62617 upstream.

We should unlock here.  This is the only place where we return from the
function with the lock held.  The caller isn't expecting it.
