I'm going to take this the slow way as it probably doesn't affect any
existing DTS so can wait a while and taking it via the fixes
branch would slow down the rest of the series.

I am keen though to cut down how many patches are in revisions
though so I've picked this one up today. Please rebase on
my tree before sending v5 to pick this up.

Applied to the togreg branch of iio.git

Thanks,
Jonathan
