Hi Billy,

Series applied to the togreg branch of iio.git and pushed out as testing for
0-day to poke at it.

Note the fix for platform_set_drvdata() is in the fixes branch so there will
be a bit of mess around context for patch 1 but that should all resolve in
a trivial fashion.

Thanks,

Jonathan
