Hi Lars,
Thanks for your review.
Should I create a new version of this patch whithout the whitespace
issues?
Generally question: What is the next step? Do you include the reviewed
patch into the iio.git repository? And do you submit the patches to the
mainline repository?
Sorry for the basic questions, currently I try to understand the whole
flow of the patch flow :)
