From ac8f7c4894bea3ae1af31e78fea31b1ba3347834 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 22 Nov 2012 19:37:17 +0000 Subject: [PATCH] drm: tegra: Use framebuffer pitch as line stride Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.
