For hwmon drivers using the hwmon_device_register_with_info() API, it is desirable to have a generic notification mechanism available. This mechanism can be used to notify userspace as well as the thermal subsystem if the driver experiences any events, such as warning or critical alarms. Implement hwmon_notify_event() to provide this mechanism. The function generates a sysfs event and a udev event. If the device is registered with the thermal subsystem and the event is associated with a temperature sensor, also notify the thermal subsystem that a thermal event occurred.
