From 818ed961e6ee7988829918b5dc41da14a05f5bc5 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 15 Jun 2015 12:33:54 +0200 Subject: [PATCH] drm/i915: Make setting color key atomic. By making color key atomic there are no more transitional helpers. The plane check function will reject the color key when a scaler is active.
