[PATCH 2/4] ABI: sysfs-class-hwmon: document missing humidity attributes

[Javier Carrasco]

All these attributes already exist and are used by the hwmon subsystem,
but they still must be documented.

The missing attributes are the following:
- humidityY_alarm
- humidityY_fault
- humidityY_label
- humidityY_max
- humidityY_max_hyst
- humidityY_min
- humidityY_min_hyst

Add the missing humidity attributes to the ABI documentation according
to their current usage and access rights in the hwmon subsystem.
