Re: [PATCH 1/1] iio: atlas-ezo: Fix humidity channel read support

Hi Joshua, Andy,

Thanks for the review and feedback.

I checked the Git history and found that the channel type check was already present
in commit dc3ebfc ("iio: chemical: atlas-ezo-sensor: add humidity sensor support").
It was not removed when humidity sensor support was introduced, and
I couldn't find any commit message explaining the original intent of the check.

Regarding the potential I2C read issue reported by Sashiko,
I'll investigate it and address it in a separate patch series.

I'll also omit the cover letter for future single-patch submissions.

Thanks,
Nikhil

The atlas_ezo_read_raw() function rejects channels that are not of
type IIO_CONCENTRATION, preventing the relative humidity channel
from reading raw and scale values.

Remove the early channel type check to allow both concentration
and relative humidity channels to reach the mask-specific handling.
Have you checked the Git history on this change? Anything interesting there?
