From ca0241a55f4f2d3a76e6753d2442b262264b938f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 8 Mar 2017 16:33:34 +0200 Subject: [PATCH] Revert "drm/i915: Ignore panel type from OpRegion on SKL" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit bb10d4ec3be4b069bfb61c60ca4f708f58f440f1. Since commit c8ebfad7a063 ("drm/i915: Ignore OpRegion panel type except on select machines") we ignore the OpRegion panel type except for specific machines (handled via a DMI match), so having SKL explicitly excluded from using the OpRegion panel type is redundant. So let's remove the SKL check.
