Subject: [PATCH 2/5] SCSI: remove unnecessary NULL test
Date: Wed, 23 Sep 2009 16:15:32 +0200 [thread overview]
Message-ID: <1253715335-6723-2-git-send-email-jirislaby@gmail.com> (raw)
In-Reply-To: <1253715335-6723-1-git-send-email-jirislaby@gmail.com>
Stanse found that c3cn is poked many times around in
cxgb3i_conn_pdu_ready, there is no need to check if it is NULL.
Remove the test.
