No objection, but the new attributes also need to be added to the ABI
documentation at
Documentation/ABI/testing/sysfs-class-hwmon and
Documentation/hwmon/sysfs-interface.rst

Which made me notice that humidityX_alarm isn't documented either.
Please document that attribute as well while you are at it.

Thanks,
Guenter
