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 ;)
It was so obviously a fix I didn't initially check if it was a 'real' bug or not. oops.
