I don't think a single well-known bus name would work, since it's very
common for a system to have multiple DDC busses, since they have multiple
video connectors.

However, representing each physical connector as a jack object to user-
space (perhaps related to media controller, or a cross-subsystem extension
of the ALSA jack objects?) and associating the I2C bus ID (or some more
abstract display-oriented ID) with it would make sense.
