Hi,

This one seems simple enough and entirely standard that I'll take
it without a dt review. As ever one is welcome, but feels like
it would be wasting Rob / Mark or anyone elses time!

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

Thanks,

Jonathan
