From 8a8f7f44a1b704c482f77a0d31cbcdf1af062263 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Mon, 1 Jun 2015 12:49:55 +0200 Subject: [PATCH] drm/i915: do not wait for vblank when crtc is off This can happen when turning off a sprite plane. Because the crtc state is not yet always swapped correctly and transitional helpers are used the crtc state cannot be relied on.
