Hi Everyone,

This is the second iteration of the $subject patch series and its original

In the meantime I have updated the patches and tested them on a system with
a couple of ACPI thermal zones. No differences in functionality after applying
the patches have been observed.

The update is mostly related to adding extra locking around trip point
temperature updates and some hardening of the .get_trend() callback routine
against invalid trip point indices.

Please see patch changelogs for details.

Thanks!
