It looks like this should read:
struct device *dev = idev->parent;

That said, I think this kind of typo is very easy with the current
naming schema.
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.

Best regards,
Martin
