Subject: Re: [PATCH net] net: phy: marvell10g: fix null pointer dereference

> Commit c3e302edca24 ("net: phy: marvell10g: fix temperature sensor on 2110")
> added a check for PHY ID via phydev->drv->phy_id in a function which is
> called by devres at a time when phydev->drv is already set to null by
> phy_remove function.
> This null pointer dereference can be triggered via SFP subsystem with a
> SFP module containing this Marvell PHY. When the SFP interface is put
> down, the SFP subsystem removes the PHY.
