From b4f2bf4c02b27f31e68cbd00fa7ef868061ac2eb Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Thu, 26 Feb 2015 09:44:45 +0200 Subject: [PATCH] drm/i915: Look at staged config when fixing pipe_src_w for LVDS The code in function intel_crtc_compute_config() that evens pipe_src_w if necessary would look at the current config instead of the staged one when deciding if there is an LVDS encoder in use. This could potentially lead to the value not being updated, if during the modeset a crtc wasn't driving an LVDS encoder.
