Commitc3e302edca("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
