Hello James Smart,
This is a semi-automatic email about new static checker warnings.
The patch f358dd0ca26c: "scsi: lpfc: NVME Target: Base modifications"
from Feb 12, 2017, leads to the following Smatch complaint:
drivers/scsi/lpfc/lpfc_mem.c:650 lpfc_sli4_nvmet_alloc()
warn: variable dereferenced before check 'dma_buf->iocbq' (see line
649)
drivers/scsi/lpfc/lpfc_mem.c
648 dma_buf->iocbq = lpfc_sli_get_iocbq(phba);
649 dma_buf->iocbq->iocb_flag = LPFC_IO_NVMET;
^^^^^^^^^^^^^^^^^^^^^^^^^
Dereference.
650 if (!dma_buf->iocbq) {
^^^^^^^^^^^^^^
Check.
651 kfree(dma_buf->context);
652 pci_pool_free(phba->lpfc_drb_pool, dma_buf->dbuf.virt,
regards,
dan carpenter
