 I understand the idea of your patch but I also see that you do at least to
 major changes. One is to set the thermal_device.devdata. The second is to
 split your internal reference private_data into driver_data and pzone_data.
 Is it possible to split this patch into two, one per modification? So it is
 easier to review your changes?
yes agreed..the kind of patch restructuring suggested by you makes sense.
