Subject: [PATCH v3 0/4] iio: pressure: dps310: support negative temperature values

This patch set fixes the reading of negative temperatures (returned in
millidegree celsius). As this requires a change of the error handling
other functions are aligned with this.
In addition a small code simplification for reading the scale factors
for temperature and pressure is included.

---
Changes in v2:
 - include fixes tag
 - Split up patch
 - introduce variables for intermediate results in functions
 - simplify scale factor reading

Changes in v3:
 - fix locking issues reported in https://lore.kernel.org/all/cbdafb33-fd3b-47ad-a678-83fa92475278@moroto.mountain/

Thomas Haemmerle (4):
  iio: pressure: dps310: support negative temperature values
  iio: pressure: dps310: introduce consistent error handling
  iio: pressure: dps310: consistently check return value of
    `regmap_read`
  iio: pressure: dps310: simplify scale factor reading
