[PATCH v2 1/4] hwmon: chipcap2: fix channels in humidity alarm notifications

[Javier Carrasco]

hwmon_notify_event() expects the channel number as its last argument,
taken into account with the type parameter that it is a humidity sensor
type. Given that this device only provides one humidity channel, 0 must
be passed. The custom construct to enumerate the channels makes wrong
assumptions by listing all types together (temperature and humidity).

Remove the custom channel enumeration and pass the right channel to
hwmon_notify_event() for hwmon_humidity_min_alarm and
hwmon_humidity_max_alarm.
