Subject: [PATCH] drm/i915: disable sdvo pixel multiplier cross-check for HAS_PCH_SPLIT
Date: Mon, 10 Jun 2013 09:25:40 +0200	[thread overview]
Message-ID: <1370849140-10669-1-git-send-email-daniel.vetter@ffwll.ch> (raw)

We don't (yet) have proper pixel multiplier readout support on pch
split platforms, so the cross check will naturally fail.
