Subject: [PATCH 11/16] qla2xxx: Remove a dead assignment in qla24xx_build_scsi_crc_2_iocbs().
Date: Tue, 25 Jun 2013 11:27:26 -0400 [thread overview]
Message-ID: <1372174051-4211-12-git-send-email-saurav.kashyap@qlogic.com> (raw)
In-Reply-To: <1372174051-4211-1-git-send-email-saurav.kashyap@qlogic.com>
From: Bart Van Assche <bvanassche@acm.org>
Since the value of cur_seg is not used and since scsi_prot_sglist()
has no side effects it is safe to remove the statement
"cur_seg = scsi_port_sglist(cmd)". Detected by Coverity.
