Subject: [PATCH 4/7] drm/ttm/drivers: call the bind function directly.
Date: Thu, 17 Sep 2020 14:30:37 +1000	[thread overview]
Message-ID: <20200917043040.146575-5-airlied@gmail.com> (raw)
In-Reply-To: <20200917043040.146575-1-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

Now the bind functions have all the protection explicitly the
drivers can just call them directly, and the api can be unexported
