Thanks to bugreport 216655 on bugzilla, the contents of the fan/thermal sensor buffers could be almost completely decoded. It was also found out that newer Dell notebooks support a new DDV WMI interface version, which just adds a additional method.
The first patch adds support for this new DDV WMI interface version, while the second patch simplifies error handling then dealing with empty buffers. The fourth patch adds a module param useful for testing the driver on hardware exposing an unsupported DDV WMI interface version. The last patch finally adds support for exposing the sensor values over a standard hwmon interface.
The patch series was tested on a Dell Inspiron 3505, with the hwmon patch being tested by multiple people over bugzilla and email. Those who tested the final version of the hwmon patch are credited with Tested-by tags.
