Hi,

I'm afraid that a similar patch was sent by Shraddha Barke back at the end
of December.  It just missed the last merge window so can currently only
be found in the testing branch of iio.git.

Thanks anyway. It is always amazing how long code can sit in a given state
before several patches turn up for it in a couple of weeks!
