From 9f6151c9039084e18c118831779a99ac8f29e39c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 9 Mar 2016 19:07:24 +0200 Subject: [PATCH] drm/i915: Pass the correct crtc state to .update_plane() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pass the current crtc state, not the old crtc state, to the .update_plane() hook. Noticed on BSW when PRIMSIZE was getting programmed to a stale value which produced utter garbage on screen eg. wwhen going from 1920x1080 to 1024x768.
