Changes in v4:
- Add explicit formula into comments of hdc3020_thresh_get_temp and
  hdc3020_thresh_get_hum
- Add explicit division by 5 into calculations in hdc3020_thresh_get_temp
  and hdc3020_thresh_get_hum
- Link to v3: https://lore.kernel.org/r/20251013-hdc3020-units-fix-v3-0-b21fab32b882@liebherr.com

Changes in v3:
- Fix verbose comment for define HDC3020_THRESH_FRACTION (Javier)
- Embed prescale into define HDC3020_THRESH_FRACTION to make the division
  by 5 calculation in threshold calculations explicit. (Andy)
- Add resulting units into comments again in hdc3020_thresh_get_temp and
  hdc3020_thresh_get_hum (Andy)
- Link to v2: https://lore.kernel.org/r/20250901-hdc3020-units-fix-v2-0-082038a15917@liebherr.com

Changes in v2:
- Added explanation what is wrong at the moment into commit msg
- Added define HDC3020_THRESH_FRACTION and comment at the beginning of the
  code.
- Use MILLI for instead of hardcoded 1000.
- Link to v1: https://lore.kernel.org/r/20250821-hdc3020-units-fix-v1-0-6ab0bc353c5e@liebherr.com

Hi Dimitri,

I think this covers the last bits of feedback so I'll queue it up in the
fixes-togreg branch of iio.git.  I'll probably not send a pull request
for that for a few more days though so there is still time for additional
feedback.

Also marked for stable.

Thanks

Jonathan
