[PATCH v1 01/13] ACPI: thermal: Add device list to struct acpi_thermal_trip

Rafael J. Wysocki
2023-09-21T18:10:47Z

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The device lists present in struct acpi_thermal_passive and struct
acpi_thermal_active can be located in struct acpi_thermal_trip which
then will allow the same code to be used for handling both the passive
and active trip points, so make that change.

No intentional functional impact.
