Unless I am mistaken this function boils down to:

You do the vconfig configuration when the video routing changes. But isn't this
configuration a one-time thing? E.g. something you do only when initializing the
board?
At least in the cxusb code the cfg_in value is constant and not dependent on what
input is chosen.
If this is true, then you should add the core init op instead. And as a bonus you
can turn on generic_mode if the init op is called instead of having to add it
to the platform data.
