The caller of the function thermal_zone_device_register_with_trips() can pass a thermal_zone_params structure parameter. This one is used by the thermal core code until the thermal zone is destroyed. That forces the caller, so the driver, to keep the pointer valid until it unregisters the thermal zone if we want to make the thermal zone device structure private the core code. As the thermal zone device structure would be private, the driver can not access to thermal zone device structure to retrieve the tzp field after it passed it to register the thermal zone. So instead of forcing the users of the function to deal with the tzp structure life cycle, make the usage easier by allocating our own thermal zone params, copying the parameter content and by freeing at unregister time. The user can then create the parameters on the stack, pass it to the registering function and forget about it. Signed-off-by:
