Hi Rafael,

could you wait before applying I would like to review the series but I'm OoO ATM, coming back next week?

Hi Everyone,

This is the second iteration of the $subject patch series and its original
description below is still applicable

This patch series makes the ACPI thermal driver register thermal zones
with the help of thermal_zone_device_register_with_trips(), so it
doesn't need to use the thermal zone callbacks related to trip points
any more (and they are dropped in the last patch).

The approach presented here is quite radically different from the
previous attempts, as it doesn't really rearrange the driver's
internal data structures, but adds the trip table support on top of
them. For this purpose, it uses an additional field in struct thermal_trip
introduced in the first patch.

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!
