Hi Mike,
This patch is missing a sign-off. Please resend with one - see
Documentation/SubmittingPatches if you want more detail.
Also more excitingly this file doesn't actually exist in the iio tree.
Guessing this patch is against Analog's tree?
If so you'll need to work on persuading them to send it upstream.
Lars, Michael? I'm going to hazard a guess that this was sat waiting
for the DMA patches to be upstreamed and might show up sometime soonish for review?
One other trivial comment inline.
