From 139467433e50926d22338e9dc754feaaf94b9db0 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 9 Feb 2011 20:01:16 +0000 Subject: drm/i915/sdvo: If we have an EDID confirm it matches the mode of the connection If we have an EDID for a digital panel, but we are probing a non-TMDS connector then we know that this is a false detection, and vice versa. This should reduce the number of bogus outputs on multi-function adapters that report the same output on multiple connectors.
