[PATCH 0/5] iio: humidity: hts221: update probe and logging implementations

[Adi Nata <adinata.softwareengineer@gmail.com>]

HTS221 is an older driver. This series groups a few small modernizations
based on current development practices.

- Report available values via read_avail()
- Add a blank line after variable declarations (style)
- Allow unknown whoami for DT fallback instead of erroring out
- Use dev_err_probe() in probe paths
- Reject calibration data that would cause division by zero

No HTS221 hardware was available. Verified with checkpatch --strict and
builds of hts221, hts221_i2c and hts221_spi. Probe and calibration
error paths were exercised against i2c-stub with register contents
pre-loaded via i2cset.
