Thanks to bugreport 216655 on bugzilla triggered by the dell-smm-hwmon driver, the contents of the sensor buffers could be almost completely decoded. Add an hwmon interface for exposing the fan and thermal sensor values. Since the WMI interface can be quite slow on some machines, the sensor buffers are cached for 1 second to lessen the performance impact. The debugfs interface remains in place to aid in reverse-engineering of unknown sensor types and the thermal buffer. Tested-by:
