I had to take a look over how "thermal_zone_device_priv()" works, and
it looks like it has nothing to do with the platform_set_drvdata() /
dev_set_drvdata() / dev->driver_data stuff.
It defines it's own `devdata` pointer.
Though, it looks like "thermal_zone_device_priv()" could potentially
be converted to use "dev->driver_data"
But that requires a bit of going through all drivers to convert them.

Anyway, for this:
