From 0d014ff344abc9c8e56cf1870ab3a144d2e2e37a Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Thu, 19 Nov 2015 16:07:17 +0100 Subject: [PATCH] drm/i915: Remove double wait_for_vblank on broadwell. wait_vblank is already set in intel_plane_atomic_calc_changes for broadwell, waiting for a double vblank is overkill.
