I am not sure whether HWMON is applicable in that case. Driver receives an async notification from the FW that an overheating occurred, so has to handle it. In that case - by printing msg and making the interface disabled for the user. FW is responsible for monitoring temperature itself. There's even no possibility to read temperature by the driver Thanks Jedrek
