From 389c5763beda623879095a10a428a02ae138bbf1 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 11 Aug 2016 10:20:23 +0300 Subject: [PATCH] drm/omap: display: Add displays in sorted order to the panel_list Keep the panel_list ordered according to aliases. The DRM connectors will be created following the panel_list. By keeping the list ordered the DRM connectors will be created in the same order regardless of the driver probe order.
