From: Dariusz Marcinkiewicz To: linux-media@vger.kernel.org, hverkuil-cisco@xs4all.nl Cc: Dariusz Marcinkiewicz Sender: linux-media-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-media@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP Pass the connector info to the CEC adapter. This makes it possible to associate the CEC adapter with the corresponding drm connector.
