+ * StorageD3Enable. But for two reasons we have added it.
+ * 1) The BIOS on a number of Dell systems have ambiguity
+ * between the same value used for _ADR on ACPI nodes GPP1.DEV0 and GPP1.NVME.
+ * GPP1.NVME is needed to get StorageD3Enable node set properly.

+ * 2) On at least one HP system StorageD3Enable is missing on the second NVME
+ disk in the system.
