[PATCH v4 0/6] iio: temperature: ltc2983: small improvements

[Nuno Sa via B4 Relay]

The v4 introduces an new dev_errp_probe() helper to deal with cases
where we want to return error pointers. The refactor in the IIO ltc2983
is an heavy user of the pattern and was the main motivation for this.

Also added two new patches so we have three users of the new
dev_errp_probe() helper.
