Subject: [PATCH 2/5] drm/ttm: add ttm_resource_fini
Date: Mon, 19 Jul 2021 13:51:42 +0200	[thread overview]
Message-ID: <20210719115145.1260-2-christian.koenig@amd.com> (raw)
In-Reply-To: <20210719115145.1260-1-christian.koenig@amd.com>

Make sure we call the common cleanup function in all
implementations of the resource manager.
