This series:
- makes the behavior of_find_device_by_node(), bus_find_device_by_of_node(), bus_find_device_by_fwnode(), etc., more consistent when provided with a NULL node/handle;
- adds kunit tests to validate the new NULL-argument behavior; and
- makes some related improvements and refactoring for the drivers/base/ kunit tests.
This series aims to prevent problems like the ones resolved in commit 5c8418cf4025 ("PCI/pwrctrl: Unregister platform device only if one actually exists").
