Ah. Sorry I was unclear on my feedback wrt to this. I was just
looking for a statement in the commit message to say that you were
doing this to allow for consumers such as the iio/hwmon bridge.
I wasn't expecting any change to the example.
+ the supplies as per reply on previous version I just sent.
