Hmm. I wondered a bit about this one. It's a correct patch in of
itself but the interface in question doesn't even vaguely conform
to any of defined IIO ABI.  Anyhow, it's still and improvement so
I'll take it.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

I also added the removal of the header define which is no
longer used.

Please note, following discussions with Michael, I am going to send
an email announcing an intent to drop these meter drivers next
cycle unless someone can provide testing for any attempt to
move them out of staging.  I'm still taking patches on the basis
that 'might' happen - but I wouldn't focus on these until we
have some certainty on whether they will be around long term!
