Browse source 
881     	case LWS_CALLBACK_MQTT_UNSUBSCRIBE_TIMEOUT:
>>>     CID 392688:    (REVERSE_INULL)
>>>     Null-checking "wsi" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
882     		if (!wsi || !wsi->mqtt)
883     			return -1;

wsi can't be NULL for a callback specific to a wsi.
