Subject: [patch] caif: unlock on error path in cfserl_receive()
Date: Wed, 26 May 2010 17:16:48 +0200 [thread overview]
Message-ID: <20100526151648.GA15439@bicker> (raw)
There was an spin_unlock missing on the error path. The spin_lock was
tucked in with the declarations so it was hard to spot. I added a new
line.
