OK, I replaced the function with:
+static int srp_init_qp(struct srp_target_port *target,
+ struct ib_qp *qp)
+{
+ struct ib_qp_attr *attr;
+ int ret;
+
+ attr = kmalloc(sizeof *attr, GFP_KERNEL);
+ if (!attr)
+ return -ENOMEM;
+
+ ret = ib_find_cached_pkey(target->srp_host->dev,
+ target->srp_host->port,
+ be16_to_cpu(target->path.pkey),
+ &attr->pkey_index);
+ if (ret)
+ goto out;
+
+ attr->qp_state = IB_QPS_INIT;
+ attr->qp_access_flags = (IB_ACCESS_REMOTE_READ |
+ IB_ACCESS_REMOTE_WRITE);
+ attr->port_num = target->srp_host->port;
+
+ ret = ib_modify_qp(qp, attr,
+ IB_QP_STATE |
+ IB_QP_PKEY_INDEX |
+ IB_QP_ACCESS_FLAGS |
+ IB_QP_PORT);
+
+out:
+ kfree(attr);
+ return ret;
+}
