Subject: [PATCH v3 02/20] drm/tests: Introduce a config option for the KUnit helpers
Date: Thu, 01 Dec 2022 16:11:33 +0100	[thread overview]
Message-ID: <20221123-rpi-kunit-tests-v3-2-4615a663a84a@cerno.tech> (raw)
In-Reply-To: <20221123-rpi-kunit-tests-v3-0-4615a663a84a@cerno.tech>

Driver-specific tests will need access to the helpers without pulling
every DRM framework test. Let's create an intermediate Kconfig options
for the helpers.
