From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
After introducing acpi_dev_parent() in commit 62fcb99bdf10 ("ACPI: Drop parent field from struct acpi_device"), it is better to use it instead of accessing the dev.parent field in struct acpi_device directly.
Modify acpi_node_get_parent() accordingly.
