From 548ee15b38ff5f6d7561f9e633efa20e7d7383b6 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Tue, 21 Apr 2015 17:13:02 +0300 Subject: [PATCH] drm/i915: Don't pretend we can calculate multiple pipe_configs The code in intel_modeset_pipe_config() still needs changes before it can calculate more than just one pipe_config, and pretending it can will only make those changes more difficult.
