What to do if a value is found to be invalid, depends on the type of the sysfs attribute that is being set. If it is a continuous setting like a tempX_max or inX_max attribute, then the value should be clamped to its -limits using SENSORS_LIMIT(value, min_limit, max_limit). If it is not -continuous like for example a tempX_type, then when an invalid value is -written, -EINVAL should be returned. +limits using clamp_val(value, min_limit, max_limit).
