But it is the case here, because the i2c driver knows about the device
tree, and thus can pass the device tree node and the adapter struct to
the enumeration function.
The driver should still do i2c_add_numbered_adapter() when using the
non-OF platform device binding, in which case it gets the bus number
from the platform data.
