That I'll skip after all...
Note that since the context of the switch descriptor is always copied
during registration, the driver_data is not going to be the same for
every switch.
The structure is actually filled in two separate functions, so the
change is not straightforward. We can still change that of course, but
it's out side the scope of this series, so it needs to be done
separately.
