From 3ba35e53cfbad79ba288a514b01b41a46fc8dc7f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 23 Mar 2017 21:27:11 +0200 Subject: [PATCH] drm/i915: Eliminate ironlake_update_primary_plane() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The effective difference between i9xx_update_primary_plane() and ironlake_update_primary_plane() is only the HSW/BDW DSPOFFSET special case. So bring that over into i9xx_update_primary_plane() and eliminate the duplicated code.
