Hi Jim,

thanks for the note.

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.
