scsi: lpfc: code cleanups in NVME initiator base
This patch addresses the smatch issues identified by Dan Carpenter in http://www.spinics.net/lists/linux-scsi/msg105663.html The issues are: drivers/scsi/lpfc/lpfc_hbadisc.c:316 lpfc_dev_loss_tmo_handler() warn: we tested 'vport->load_flag & 2' before and it was 'false' Action: removed item from test drivers/scsi/lpfc/lpfc_hbadisc.c:701 lpfc_work_done() warn: test_bit() takes a bit number Action: changed definition so bit number drivers/scsi/lpfc/lpfc_hbadisc.c:2206 lpfc_mbx_cmpl_fcf_scan_read_fcf_rec() error: uninitialized symbol 'vlan_id'. drivers/scsi/lpfc/lpfc_hbadisc.c:2582 lpfc_mbx_cmpl_fcf_rr_read_fcf_rec() error: uninitialized symbol 'vlan_id'. drivers/scsi/lpfc/lpfc_hbadisc.c:2683 lpfc_mbx_cmpl_read_fcf_rec() error: uninitialized symbol 'vlan_id'. Action: initilized value drivers/scsi/lpfc/lpfc_hbadisc.c:4025 lpfc_register_remote_port() error: we previously assumed 'rdata' could be null (see line 4023) Action: refactored check block drivers/scsi/lpfc/lpfc_hbadisc.c:4613 lpfc_sli4_dequeue_nport_iocbs() error: double unlock 'irq:' Action: removed inner irq reference Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Martin K.
