This series:
1. 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;
2. adds kunit tests to validate the new NULL-argument behavior; and
3. 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").
