It was pointed out during the review [1] of commit e66bf63a7f67 ("net:
dsa: qca8k: skip MDIO bus creation if its OF node has status =
"disabled"") that we now leak a reference to the "mdio" OF node if it is
disabled.
This is only a concern when using dynamic OF as far as I can tell (like
probing on an overlay), since OF nodes are never freed in the regular
case. Additionally, I'm unaware of any actual device trees (in
production or elsewhere) which have status = "disabled" for the MDIO OF
node. So handling this as a simple enhancement.

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.
