That one is a checkpatch defect.

The list_entry( use is really ugly too
with bad indentation on the following line.

Look at the entire function:

static u32 extract_qos_list(struct nic *nic, struct list_head *head)
{
	struct qos_cb_s *qcb = &nic->qos;
	struct qos_entry_s *entry;
	int i;

	INIT_LIST_HEAD(head);

	for (i = 0; i < QOS_MAX; i++) {
		if (qcb->csr[i].enabled) {
			if (qcb->csr[i].qos_buf_count < qcb->qos_limit_size) {
				if (!list_empty(&qcb->qos_list[i])) {
					entry = list_entry(
					qcb->qos_list[i].prev,
					struct qos_entry_s, list);
					list_move_tail(&entry->list, head);
					qcb->csr[i].qos_buf_count++;

					if (!list_empty(&qcb->qos_list[i]))
						netdev_warn(nic->netdev,
							    "Index(%d) is piled!!\n",
							    i);
				}
			}
		}
	}

	return 0;
}

Please consider rewriting the function
to reduce unnecessary indentation.

Something like:

static u32 extract_qos_list(struct nic *nic, struct list_head *head)
{
	struct qos_cb_s *qcb = &nic->qos;
	int i;

	INIT_LIST_HEAD(head);

	for (i = 0; i < QOS_MAX; i++) {
		if (!qcb->csr[i].enabled ||
		    qcb->csr[i].qos_buf_count >= qcb->qos_limit_size)
			continue;

		if (!list_empty(&qcb->qos_list[i])) {
			struct qos_entry_s *entry;

			entry = list_entry(qcb->qos_list[i].prev,
					   struct qos_entry_s, list);
			list_move_tail(&entry->list, head);
			qcb->csr[i].qos_buf_count++;

			if (!list_empty(&qcb->qos_list[i]))
				netdev_warn(nic->netdev, "Index(%d) is piled!!\n",
					    i);
		}
	}

	return 0;
}
