Staging: iio: max1363 Fix two bugs in single_channel_from_ring
This patch contains fixes for the two bugs Michael pointed
out last week. As the other suggestion Michael made is
not a bug fix (just a much more sensible way of handling
things), I'll do that as a separate patch soon.
The bugs were introduced with the abi changes.
