From 25928a395e89423c2d8f8a8620dc213702a05105 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Mon, 17 Mar 2014 11:27:17 +0100 Subject: [PATCH] drm/exynos: delay fbdev initialization until an output is connected In case fbdev is initialized before any output is connected, fb resolution defaults to 1024x768. After that any output with bigger resolution is ignored and fbdev is not displayed. The patch postpones fbdev initialization to avoid such situation.
