From 7bf93c73adb28d8db6b34c27d3edd96337a2d366 Mon Sep 17 00:00:00 2001 From: Ajay Kumar Date: Wed, 30 Jul 2014 12:02:15 +0200 Subject: [PATCH] drm/panel: Provide convenience wrapper for .get_modes() Add a convenience wrapper for the struct drm_panel_funcs' .get_modes() function so that not every driver needs to check that the panel driver implements the function before calling it.
