I don't understand what the above means, sorry. Normally the address
ranges for devices are supplied via resources when the device is
registered.

This looks like it might be part of the previous change to merge
separate playback and capture instances of the controller into one
device rather than a separate change? But perhaps what this is saying
is also that the controller instances aren't actually totally separate
after all and the prior change maps well onto the hardware...
