Subject[069/139] drm/radeon/kms: fix tv dac conflict resolver
2.6.33-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alex Deucher <alexdeucher@gmail.com>

commit 08d075116db3592db218bfe0f554cd93c9e12505 upstream.

On systems with the tv dac shared between DVI and TV,
we can only use the dac for one of the connectors.
However, when using a digital monitor on the DVI port,
you can use the dac for the TV connector just fine.
Check the use_digital status when resolving the conflict.

Fixes fdo bug 27649, possibly others.
