Subject: [PATCH 01/14] drm/bochs: encoder cleanup
Date: Wed, 19 Dec 2018 12:51:14 +0100	[thread overview]
Message-ID: <20181219115127.31359-2-kraxel@redhat.com> (raw)
In-Reply-To: <20181219115127.31359-1-kraxel@redhat.com>

Most unused callbacks can be NULL pointers these days.
Drop a bunch of empty encoder callbacks.
