fixed the following coccicheck:
./drivers/scsi/scsi_transport_iscsi.c:436:60-61: WARNING opportunity for
kobj_to_dev()
./drivers/scsi/scsi_transport_iscsi.c:1128:60-61: WARNING opportunity
for kobj_to_dev()
./drivers/scsi/scsi_transport_iscsi.c:4043:61-62: WARNING opportunity
for kobj_to_dev()
./drivers/scsi/scsi_transport_iscsi.c:4312:61-62: WARNING opportunity
for kobj_to_dev()
./drivers/scsi/scsi_transport_iscsi.c:4456:61-62: WARNING opportunity
for kobj_to_dev()
