+Subject: net: phy: Fix PHY unbind crash
+
+From: Florian Fainelli <f.fainelli@gmail.com>
+
+commit 7b9a88a390dacb37b051a7b09b9a08f546edf5eb upstream.
+
+The PHY library does not deal very well with bind and unbind events. The first
+thing we would see is that we were not properly canceling the PHY state machine
+workqueue, so we would be crashing while dereferencing phydev->drv since there
+is no driver attached anymore.
