From d393acce7b3f046a1086362317a05f2cac01fa89 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 15 Dec 2023 15:39:12 +0800 Subject: drm/tests: Switch to kunit devices 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.
