Applied to the fixes-togreg branch of

Actually, change of plan. Applied to the togreg branch of that
tree. Whilst technically more correct to have it as you say,
we are dealing with the size of a struct iio_trig ** vs
a struct iio_trig * so it isn't actually a bug, just a
less than ideal bit of code ;)
Absolutely.
It was so obviously a fix I didn't initially check if it
was a 'real' bug or not. oops.
Yes, I took this path myself as well ;-)
