Subject: [PATCH] drm/tests: Add Kunit Helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As the number of kunit tests in KMS grows further, we start to have
multiple test suites that, for example, need to register a mock DRM
driver to interact with the KMS function they are supposed to test.
Let's add a file meant to provide those kind of helpers to avoid
duplication.
