commit 1b5ea7ffb7a3bdfffb4b7f40ce0d20a3372ee405 upstream. With support for Ethernet PHY LEDs having been added, while unregistering a MDIO bus and its child device liks PHYs there may be "late" accesses to the MDIO bus. One typical use case is setting the PHY LEDs brightness to OFF for instance. We need to ensure that the MDIO bus controller remains entirely functional since it runs off the main GENET adapter clock.

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.
