From the past experiences, it is found _PCL return a reference, ex. return (_SB), when it should return "A variable-length Package containing a list of References to devices or buses" as in acpi spec. For example, it should be

Method(_PCL) {
     return (Package(){_SB})
}

Luckily linux kernel does not actually use _PCL for any purpose and it is safe to ignore it.
