Observe that acpi_get_child() doesn't need to use the helper struct acpi_find_child structure and change it to work without it. Also, using acpi_get_object_info() to get the output of _ADR for the given device is overkill, because that function does much more than just evaluating _ADR (let alone the additional memory allocation done by it). Moreover, acpi_get_child() doesn't need to loop any more once it has found a matching handle, so make it stop in that case. To prevent the results from changing, make it use do_acpi_find_child() as a post-order callback. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
