+CC Alexander who wrote this driver.

Given this one is less active than the others you've sent I'll pick it up now.
(the others will wait a few days to see if we get reviews from anyone else).

Applied to the togreg branch of iio.git and pushed out as testing for 0-day
to see if it can find anything we missed.

Thanks,

Jonathan
