Chris Wilson b66d842467 drm/i915/sdvo: Restore guess of the DDC bus in absence of VBIOS ... If the VBIOS tells us the mapping of the SDVO device onto the DDC bus, use it. However, if there is no VBIOS available that mapping is uninitialised and we should fallback to our earlier guess. Fix regression introduced in b1083333 (which in turn is a fix for the regression caused by the introduction of this guess, 14571b4).
