Hmm, even with no governors and unregistered thermal sysfs class?

IMO, thermal APIs for registering a thermal_zone/cooling_device should
yield early if thermal_init fails.
For other APIs that relies on a valid
thermal_zone_device/thermal_cooling_device pointer, nothing needs to
be changed.

what do you think?

thanks,
