[PATCH] drm/tests: Switch to kunit devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Kunit recently gained helpers to create test managed devices. This means
that we no longer have to roll our own helpers in KMS and we can reuse
them.

David, feel free to integrate that patch into your series and merge it
whenever and wherever you see fit.
