of_node_release() can not use the "%pOF" printk format to report the node name of a node when the node reference count is zero. This is because the formatter device_node_string() calls fwnode_full_name_string() which indirectly calls of_node_get(). Calling of_node_get() on the node with a zero reference count results in a WARNING and stack trace. When the reference count has been decremented to zero, this function is in the subsequent call path which frees memory related to the node. This commit resolves the unittest EXPECT errors that were created in the previous commmit.

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.
