[PATCH v2 2/2] thermal: intel: pch: Fix unexpected shutdown at critical temperature

[Kai-Heng Feng]

Like previous patch, the intel_pch_thermal device is not in ACPI
ThermalZone namespace, so a critical trip doesn't mean shutdown.

Override the default .critical callback to prevent surprising thermal
shutdoown.
