Yes.
ACPI_THERMAL_HID is automatically given to ACPI objects of the
ACPI_TYPE_THERMAL type that represent thermal zones.

This artificial device ID is used internally by the kernel and there's
no need for you to manipulate it.
In order for the ACPI thermal driver to be used, at least one thermal
zone needs to be declared in the ACPI namespace.
