Subject: [PATCH 02/12] drm/ttm: add back a reference to the bdev to the res manager
Date: Mon, 24 Jan 2022 13:25:04 +0100	[thread overview]
Message-ID: <20220124122514.1832-3-christian.koenig@amd.com> (raw)
In-Reply-To: <20220124122514.1832-1-christian.koenig@amd.com>

It is simply a lot cleaner to have this around instead of adding
the device throughout the call chain.
