Subject: [ 080/102] drm/i915: make SDVO TV-out work for multifunction devices

3.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Daniel Vetter <daniel.vetter@...ll.ch>

commit 09ede5414f0215461c933032630bf9c3a61a8ba3 upstream.

We need to track this correctly. While at it shovel the boolean
to track whether the sdvo is in tv mode or not into pipe_config.
