Nope. There is only one and it is called iio:deviceX.  Some stub functions should
(if I have gotten it right) ensure that you can have events and/or buffers.
Note that isn't as you've noticed the case mid way through this set.  Couldn't see
a cleaner way of doing this.  It only all should work after patch 5.
