Subject: [PATCH v4 06/11] qla2xxx: Increase the size of struct qla_fcp_prio_cfg to FCP_PRIO_CFG_SIZE
Date: Sun, 26 Apr 2020 20:03:05 -0700 [thread overview]
Message-ID: <20200427030310.19687-7-bvanassche@acm.org> (raw)
In-Reply-To: <20200427030310.19687-1-bvanassche@acm.org>
This patch fixes the following Coverity complaint without changing any
functionality:
CID 337793 (#1 of 1): Wrong size argument (SIZEOF_MISMATCH)
suspicious_sizeof: Passing argument ha->fcp_prio_cfg of type
struct qla_fcp_prio_cfg * and argument 32768UL to function memset is
suspicious because a multiple of sizeof (struct qla_fcp_prio_cfg) /*48*/
is expected.
memset(ha->fcp_prio_cfg, 0, FCP_PRIO_CFG_SIZE);
