There was a bit of fuzz due to crossing with the particle sensor.
Note that it changed the enum numbers so you'll need to rebuild
your own tools against the new version of the header.

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

Thanks,

Jonathan
