From: Florian Fainelli <f.fainelli(a)gmail.com> stable inclusion from stable-v5.10.181 commit e92727ed9e8b6798efc1e7ae44bbe7c44c453670 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 93e0401e0fc0c54b0ac05b687cd135c2ac38187c ] The call to phy_stop() races with the later call to phy_disconnect(), resulting in concurrent phy_suspend() calls being run from different CPUs. The final call to phy_disconnect() ensures that the PHY is stopped and suspended, too.
