From f56cd64f5f713a3013c4d980a5695c198d839671 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 18 Dec 2009 11:28:22 -0500 Subject: drm/radeon/kms: never combine LVDS with another encoder When linking multiple encoders to a connector, make sure to not link LVDS with another connector. Some bioses have the same i2c line for LVDS and VGA.
