It's been a while since I looked at other drivers but maybe the IIO maintainers have some recommendations for us (which would apply to multiple IIO drivers, not just meson_saradc). For example: I am not sure if iio_{err,warn} functions (which take a struct iio_dev pointer) have been proposed/discussed before. I think they could be useful for other drivers as well.
