From fab7c5b778b1e0ee89e75679b2d6a1405318bb11 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 9 Jun 2011 04:26:45 +0000 Subject: video: s3c-fb: move enabling channel for window This patch moves enabling channel for window, because there should be enabling channel before enabling window. If the sequence is reversed, it makes the problem in displaying images to lcd panel.
