Subject: [PATCH net-next 06/10] net: hns3: remove a redundant hclge_cmd_csq_done
Date: Fri, 29 Jun 2018 19:23:01 +0800	[thread overview]
Message-ID: <1530271385-49668-7-git-send-email-lipeng321@huawei.com> (raw)
In-Reply-To: <1530271385-49668-1-git-send-email-lipeng321@huawei.com>

From: Huazhong Tan <tanhuazhong@huawei.com>

Set complete in the first hclge_cmd_csq_done of hclge_cmd_send,
and check if complete later, unnecessary to do hclge_cmd_csq_done
again.
