We'd like to apply overlays to the root node in KUnit so we can test platform devices created as children of the root node. On some architectures (powerpc), the root node isn't marked with OF_POPULATED_BUS. If an overlay tries to modify the root node on these platforms it will fail, while on other platforms, such as ARM, it will succeed. This is because the root node is marked with OF_POPULATED_BUS by of_platform_default_populate_init() calling of_platform_default_populate() with NULL as the first argument. Loosen the requirement here so that platform devices can be created for nodes created as children of the root node via DT overlays even if the platform bus wasn't populated for the root node.

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 reStructuredText 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.
