Date: Wed, 16 Sep 2020 20:43:10 -0700 From: Florian Fainelli <f.fainelli@...il.com> To: netdev@...r.kernel.org Cc: Florian Fainelli <f.fainelli@...il.com>, andrew@...n.ch, hkallweit1@...il.com, kuba@...nel.org, davem@...emloft.net Subject: [PATCH net 2/2] net: phy: Do not warn in phy_stop() on PHY_DOWN When phy_is_started() was added to catch incorrect PHY states, phy_stop() would not be qualified against PHY_DOWN. It is possible to reach that state when the PHY driver has been unbound and the network device is then brought down.
