Hello Parav Pandit,

The patch fe2caefcdf58: "RDMA/ocrdma: Add driver for Emulex OneConnect IBoE RDMA adapter" from Mar 21, 2012, leads to the following static checker warning:

drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1426 _ocrdma_modify_qp()
warn: bool is not less than zero.

drivers/infiniband/hw/ocrdma/ocrdma_verbs.c
1411 int _ocrdma_modify_qp(struct ib_qp *ibqp, struct ib_qp_attr *attr,
1412 int attr_mask)
1413 {

  1414          int status = 0;
  1415          struct ocrdma_qp *qp;
  1416          struct ocrdma_dev *dev;
  1417          enum ib_qp_state old_qps;
  1418  
  1419          qp = get_ocrdma_qp(ibqp);
  1420          dev = get_ocrdma_dev(ibqp->device);
  1421          if (attr_mask & IB_QP_STATE)

1422 status = ocrdma_qp_state_change(qp, attr->qp_state, &old_qps);
1423 /* if new and previous states are same hw doesn't need to
1424 * know about it.
1425 */
1426 if (status < 0)

This check is never true. Based on the comment then the check should be:

		if (status == 1)
			return SOMETHING;
  1427                  return status;
  1428          status = ocrdma_mbx_modify_qp(dev, qp, attr, attr_mask);
  1429  
  1430          return status;
  1431  }

regards,
