Subject: [PATCH v4 27/27] drm/i915: use calculated state for vblank evasion

Message-ID: <1433155811-9671-28-git-send-email-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <1433155811-9671-1-git-send-email-maarten.lankhorst@linux.intel.com>

crtc->active will be gone eventually, and this check should be just as good.
