^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * This module attempts to repair or convert objects returned by the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * predefined methods to an object type that is expected, as per the ACPI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * specification. The need for this code is dictated by the many machines that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * return incorrect types for the standard predefined methods. Performing these
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * conversions here, in one place, eliminates the need for individual ACPI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * device drivers to do the same. Note: Most of these conversions are different

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 521) * Package object around the original object, creating the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 522) * correct and expected Package with one sub-object.
