I believe the series should go via your tree, yes. I had only minor
comments in the code added for the cooling device code, as it lacks the
unregistration call in the .remove callback.

Also, the DTS changes may generate conflicts with platform code. Lukasz
may probably ask Kukjin Kim to add them via the samsung tree.
