Subject: [PATCH 4/7] drm/ttm: drop unbind callback.
Date: Tue, 20 Oct 2020 11:03:16 +1000	[thread overview]
Message-ID: <20201020010319.1692445-5-airlied@gmail.com> (raw)
In-Reply-To: <20201020010319.1692445-1-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

The drivers now control this, so drop unbinding.
