Subject: [PATCH 2/3] drm/udl: introduce a macro to convert dev to udl.
Date: Fri,  5 Apr 2019 13:17:14 +1000	[thread overview]
Message-ID: <20190405031715.5959-3-airlied@gmail.com> (raw)
In-Reply-To: <20190405031715.5959-1-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

This just makes it easier to later embed drm into udl.
