Re: [PATCH 1/5] iio: humidity: hts221: report available values via read_avail()

Hi Jonathan,

Thanks for the feedback. I have checked with what Sachiko is saying is correct.
The custom attribute was in_humidity_oversampling_ratio_available while
the current on is in_humidityrelative_oversampling_ratio_available because in
industrial_core.c only has [IIO_HUMIDITYRELATIVE] = "humidityrelative".

For this humidity case in particular, would it be better to keep the legacy
implementation while adding the new read_avail()?

The other case declaration will remain changed.
