hwmon: Retire SENSORS_LIMIT
SENSORS_LIMIT and clamp_val have the same functionality, so retire SENSORS_LIMIT as it is no longer needed. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>

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.
