Subject: [PATCH v3 0/3] drivers: base: Don't match device with NULL of_node/fwnode/etc + tests

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").

Changes in v3:
 * Fix potential leak in test error case

Changes in v2:
 * CC LKML (oops!)
 * Keep "devm" and "match" tests in separate suites

Brian Norris (3):
  drivers: base: Don't match devices with NULL of_node/fwnode/etc
  drivers: base: test: Enable device model tests with KUNIT_ALL_TESTS
  drivers: base: test: Add ...find_device_by...(... NULL) tests
