From 0cb09a97d85753a372390bfc04172d980d235f2c Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Fri, 30 Jan 2015 12:17:23 +0200 Subject: [PATCH] drm/i915: Use pipe_config's cpu_transcoder for reading encoder hw state The get_config() functions for ddi and dp_mst, used to read the value of cpu_transcoder from the crtc->config instead of the state passed as an argument. On the hardware state readout path, that happens to work since the proper value is written to it before encoder->get_config() is called. However, in the check_crtc() path, the state will be read from the cpu_transcoder in the software tracking, instead of the one just read out from hw. Using the field in the supplied intel_crtc_state should do the right thing in both cases. v2: Fix intel_ddi_get_config() too.
