From e7076389f48128b00dd3f33767fb60bd3f5a06a8 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Tue, 16 Oct 2007 01:29:08 -0700 Subject: [PATCH] s3c2410fb: make use of default_display settings This patch changes mode selection to always prefer default mode if possible and always honor type of display set by default mode settings. This patch is required in case the same display modes were defined for different panels (e.g. STN and TFT).
