The first patch makes the thermal core create a copy of the trips table which is declared as a flex array to enable additional bounds checking on it. The next two patches update the ACPI thermal driver and Intel thermal drivers to take benefit of that change. In a similar pattern, patch [4/6] makes the thermal core create an internal copy of the zone ops supplied by the zone creator, so as to allow the original ops structure to be discarded after zone registration or allocated as read-only, and the next two patches update the ACPI thermal driver and Intel thermal drivers to actually do that. The other thermal drivers need not be changed, although in principle they may be simplified a bit too in the future. As usual, please refer to the individual patch changelogs for details. Thanks!
