| |
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.
