Rafael J. Wysocki d48005511a thermal: core: Move thermal zone locking out of bind/unbind functions
Since thermal_bind_cdev_to_trip() and thermal_unbind_cdev_from_trip()
acquire the thermal zone lock, the locking rules for their callers get
complicated.  In particular, the thermal zone lock cannot be acquired
in any code path leading to one of these functions even though it might
be useful to do so.

To address this, remove the thermal zone locking from both these
functions, add lockdep assertions for the thermal zone lock to both
of them and make their callers acquire the thermal zone lock instead.

No intentional functional impact.
