From 04f6ec35cbb9794bb185f58d15c7d8f326374618 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 21 Nov 2022 13:33:37 +0100 Subject: [PATCH] drm/tests: helpers: Switch to a platform_device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The device managed resources are ran if the device has bus, which is not the case of a root_device. Let's use a platform_device instead.
