David Müller 32b9dc07fb drm/i915: Fall back to bit banging mode for DVO transmitter detection
commit e4bfff54ed upstream.

As discussed in this thread
http://lists.freedesktop.org/archives/dri-devel/2013-April/037411.html
GMBUS based DVO transmitter detection seems to be unreliable which could
result in an unusable DVO port.

The attached patch fixes this by falling back to bit banging mode for
the time DVO transmitter detection is in progress.
