Subject: [PATCH 05/10] qla2xxx: Remove a dead assignment in qla24xx_build_scsi_crc_2_iocbs()
Date: Wed, 05 Jun 2013 15:06:15 +0200 [thread overview]
Message-ID: <51AF37C7.3080808@acm.org> (raw)
In-Reply-To: <51AF36BF.3030602@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_prot_sglist(cmd)". Detected by Coverity.
