be2iscsi: Fix memory corruption in MBX path

Subject: re: [SCSI] be2iscsi: Fix handling timed out MBX completion from FW
Hello Jayamohan Kallickal,
The patch 1957aa7f6246: "[SCSI] be2iscsi: Fix handling timed out MBX completion from FW" from Jan 29, 2014, leads to the following static checker warning:
drivers/scsi/be2iscsi/be_main.c:5581 beiscsi_dev_probe()
error: memset() '&phba->ctrl.ptag_state[i]->tag_mem_state' too small (24 vs 32)
drivers/scsi/be2iscsi/be_main.c
5576 for (i = 0; i < MAX_MCC_CMD; i++) {
5577 init_waitqueue_head(&phba->ctrl.mcc_wait[i + 1]);
5578 phba->ctrl.mcc_tag[i] = i + 1;
5579 phba->ctrl.mcc_numtag[i + 1] = 0;
5580 phba->ctrl.mcc_tag_available++;
5581 memset(&phba->ctrl.ptag_state[i].tag_mem_state, 0,
5582 sizeof(struct beiscsi_mcc_tag_state));
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Probably this this be change to sizeof(struct be_dma_mem struct)? It looks like we are corrupting memory a bit here.
5583 }
regards,
dan carpenter
