[PATCH 39/79] hwmon: (asb100) Fix vrm value range

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When updating vrm, the value range was not limited. This could result in more or
less random vrm values if the value provided by the user was larger than 255.
Fix by limiting the range to 0..255 using the SENSORS_LIMIT macro.
