+Subject: net: hns3: adjust hns3_uninit_phy()'s location in the hns3_client_uninit()
+
+From: Huazhong Tan <tanhuazhong@huawei.com>
+
+commit 0d2f68c7bcf4c7bbdd6f810f7b6e658f43d4461e upstream.
+
+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().
+
+Fixes: c8a8045b2d0a ("net: hns3: Fix NULL deref when unloading driver")
