Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a reference to the DT node, but does not hold a refcount on the node. The simple solution to this is to add the necessary refcounting into the MDIO bus code for all users, ensuring that on registration, the refcount is incremented, and only dropped when the MDIO bus is released. Do this for fwnodes, so we not only fix this for DT, but also other types of firmware nodes as well.

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.
