Hmm .. turns out those functions don't define dummies if CONFIG_THERMAL is not configured. How annoying. Nishant, please fix your gpio-fan patch. I am going to drop it for now. Please keep in mind that there is a secondary dependency: The thermal code can be built as module. In that case, the gpio-fan driver must either also be built as module, or its thermal registration must be disabled.
