hwmon: (f71882fg) Add support for the f71889fg (version 2)
This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.
Note that this bit of the patch:
- val = SENSORS_LIMIT(val, 0, 255);
+
+ if (data->type == f71889fg)
+ val = SENSORS_LIMIT(val, -128, 127);
+ else
+ val = SENSORS_LIMIT(val, 0, 127);
Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.
