From e948d32c54fa45cc1601c98956bdbbf5f17a3db2 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sat, 23 Jul 2022 19:57:17 +0200 Subject: video: fbdev: imxfb: Drop platform data support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit No source file but the driver itself includes the header containing the platform data definition. The last user is gone since commit 8485adf17a15 ("ARM: imx: Remove imx device directory"). So we can safely drop platform data support.
