Ah sorry I misread Mark's request. i2c-gpio will turn the platform
device ID into bus number, it can indeed not be forced through platform
data. But I don't think any other i2c bus driver allows this either. I
don't quite see the problem with setting a platform device ID even if
there's only one instance of the platform device. I have many examples
of this on my machine:
Fixed MDIO bus.0
coretemp.0
vesafb.0

So please just set the platform device ID to 0 (or whatever i2c adapter
number you want) and your problem is solved. As you just proposed
initially, actually :)
