The __of_mdiobus_register() function was storing the device node in dev.of_node without increasing its reference count. It implicitly relied on the caller to maintain the allocated node until the mdiobus was unregistered. Now, __of_mdiobus_register() will acquire the node before assigning it, and of_mdiobus_unregister_callback() will be called at the end of mdio_unregister(). Drivers can now release the node immediately after MDIO registration. Some of them are already doing that even before this patch.

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.
