Subject: [PATCH 3/8] orinoco: Fix memory leak and unneeded unlock in orinoco_join_ap()
Date: Fri, 23 Sep 2005 04:18:06 -0400	[thread overview]
Message-ID: <E1EIikw-0003op-O6@gnu.org> (raw)

Signed-off-by: Pavel Roskin <proski-mXXj517/zsQ@public.gmane.org>

Fix memory leak and unneeded unlock in orinoco_join_ap()

If orinoco_lock() fails, the code would still run orinoco_unlock(),
instead of freeing the allocated memory.  Found by sparse.
