[PATCH v5 0/2] iio: temperature: ltc2983: small improvements

[Nuno Sa]

Hi Jonathan,

As suggested by you, v5 only has the regulator stuff. I'll send another
series for the new dev_errp_helper().

---
Changes in v5:
- Dropped patches 1,2,5 and 6.
- Link to v4: https://lore.kernel.org/all/20240328-ltc2983-misc-improv-v4-0-0cc428c07cd5@analog.com/
