Subject: [PATCH 010/283] net: hns3: adjust hns3_uninit_phy()'s location in the
hns3_client_uninit()
mainline inclusion
from mainline-v5.3-rc1
commit 0d2f68c7bcf4c7bbdd6f810f7b6e658f43d4461e
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EJ0A
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0d2f68c7bcf4c7bbdd6f810f7b6e658f43d4461e
--------------------------------
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")
