no driver that would ever bind a counter device, is there? So
/sys/bus/counter/driver is always empty.
There used to be a time when GKH said that we do not want new driver
classes. And all new subsystems should use bus since bus is a superset
of class. This restriction has been eased since then.
But it was around when the IIO subsystem was merged and since the
counter subsystem originated from the IIO subsystem I assume it just
copied this.
