Sorry, I ended up taking Cristian's patch for the same issue.

No particular reason other than which email I hit first!

Hi Vladimir,

This particular driver has recently moved out of staging and gained support
for some additional parts.  Still the particular issue was there still.

I applied your patch by hand to the moved driver and the additional case
of the same thing that was write next to this.

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

Thanks,

Jonathan
