Hi All,
If thermal_class is not registered, the whole thermal framework is basically unusable, because the governors are not there and its sysfs interface is not present.
In that case it doesn't make sense to register thermal zones and cooling devices, because they cannot be used as expected anyway, so make it possible to fail the registration of these things if the registration of thermal_class has failed.
To that end, make sure that the private pointer of a class is NULL when that class is not registered with the driver core (patch [1/2]).
Next, make the thermal framework check the value of the thermal_class' private pointer against NULL and fail the registration of thermal zones and cooling devices when it is NULL (patch [2/2]).
Thanks!
