Subject: [PATCH 7/7] drm/ttm: move last binding into the drivers.
Date: Tue, 20 Oct 2020 11:03:19 +1000	[thread overview]
Message-ID: <20201020010319.1692445-8-airlied@gmail.com> (raw)
In-Reply-To: <20201020010319.1692445-1-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

This moves the call to tt binding into the driver move,
and drops the driver callback.

Signed-off-by: Dave Airlie <airlied@redhat.com>
