[PATCH v3 1/4] hwmon: (lm85) Use macro to determine if VID5 is configured

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

 



ADT7463 and ADT7468 optionally support VID5 instead of the standard +12V
measurement input. Use a macro to detect configuration instead of hardcoding it
several times.
