From c465613bc97ed996f2278116c79d2c6adec3998d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 29 Oct 2015 21:25:56 +0200 Subject: [PATCH] drm/i915: Check for CPT and not !IBX in ironlake_disable_pch_transcoder() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ironlake_enaable_pch_transcoder() checks for CPT to see if it should enable the timing override chicken bit, but ironlake_disable_pch_transcoder() checks for !IBX to see if it should clear the same bit. Change ironlake_disable_pch_transcoder() to check for CPT as well to keep the two sides consistent.
