Hi Everyone,

This is a continuation of

https://lore.kernel.org/linux-pm/4920970.GXAFRqVoOG@rjwysocki.net/

that eliminates a couple of races related to thermal zone initialization
and system suspend, cleans up thermal zone updates handling during thermal
zone and cooling device initialization and generally switches over the
thermal core to using guards for locking.

Please see the individual patch changelogs for details.

The patches in this series only received minimum testing (hence RFC), but
all of these changes make sense IMV.

Thanks!
