On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.

commit 2c6315da6a1657a49e03970a4084dc3d1958ad70 upstream.

On systems where the temperature sensor is actually used, the BIOS is
likely to have locked the alarm registers.  In that case, all writes
through the corresponding sysfs files would be silently ignored.

To prevent this, detect the locks and make the affected sysfs files
read-only.

The documentation lists standard numbers and chip names in excruciating detail, but that's all it does.

Functions set_fan_min() and set_fan_div() assume that the fan_div values have already been read from the register. The driver currently doesn't initialize them at load time, they are only set when function via686a_update_device() is called. This means that set_fan_min() and set_fan_div() misbehave if, for example, "sensors -s" is called before any monitoring application (e.g. "sensors") is has been run. Fix the problem by always initializing the fan_div values at device bind time.
