Subject: [PATCH 5.4 39/43] net: phy: Do not warn in phy_stop() on PHY_DOWN
Date: Fri, 25 Sep 2020 14:48:51 +0200	[thread overview]
Message-ID: <20200925124729.471990495@linuxfoundation.org> (raw)
In-Reply-To: <20200925124723.575329814@linuxfoundation.org>

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit 5116a8ade333b6c2e180782139c9c516a437b21c ]

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.

Fixes: 2b3e88ea6528 ("net: phy: improve phy state checking")
