drm/i915: Fix DDC bus selection for multifunction SDVO Multifunction SDVO cards stopped working after 14571b4, and would report something that looked remarkably like an ADD2 SPD ROM instead of EDID. This appears to be because DDC bus selection was utterly horked by that commit; controlled_output was no longer always a single bit, so intel_sdvo_select_ddc_bus would pick bus 0, which is (unsurprisingly) the SPD ROM bus, not a DDC bus. So, instead of that, let's just use the DDC bus the child device table tells us to use. I'm guessing at the bitmask and shifting from VBIOS dumps, but it can't possibly be worse. cf. https://bugzilla.redhat.com/584229 Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net>
