Subject: [PATCH 02/13] omapfb: panel-sony-acx565akm: remove support for
 platform data
Date: Thu,  3 Nov 2022 15:46:39 -0700

X-Mailing-List: linux-fbdev@vger.kernel.org

There are no users of panel_acx565akm_platform_data in the mainline
kernel so support for it can be removed from the panel driver.
