It 'should' but it doesn't which is part of the reason it's still in staging
after all these years.

Ideally clean up the driver. If you are willing that would be great, if not
would you be able to test changes made by someone else? You are first person
in years that I know has one! :) I can't remember how far this driver is
from being ready to move out of staging, but I can probably find some time
to do a thorough review of that in next few weeks.
That may require extra ABI definitions possibly including the real and imag
modifiers at which point your patch to libiio would be correct.
