Message-ID: <1559034182-24737-12-git-send-email-tanhuazhong@huawei.com> Date: Tue, 28 May 2019 17:03:01 +0800 From: Huazhong Tan <tanhuazhong@...wei.com> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <salil.mehta@...wei.com>, <yisen.zhuang@...wei.com>, <linuxarm@...wei.com>, Huazhong Tan <tanhuazhong@...wei.com>, Peng Li <lipeng321@...wei.com> Subject: [PATCH net-next 11/12] net: hns3: adjust hns3_uninit_phy()'s location in the hns3_client_uninit() hns3_uninit_phy() should be called before checking HNS3_NIC_STATE_INITED flags, otherwise when this checking fails, there is nobody to call hns3_uninit_phy().
