From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> 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. Suggested-by: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Signed-off-by: Rafael J.
