Subject: [PATCH RESEND 09/13] omapfb: connector-analog-tv: remove support for
 platform data
Date: Thu,  3 Nov 2022 20:16:38 -0700

Precedence: bulk
List-ID: <linux-fbdev.vger.kernel.org>
X-Mailing-List: linux-fbdev@vger.kernel.org

There are no users of connector_atv_platform_data in the mainline
kernel so support for it can be removed from the panel driver.
