Subject: Re: [PATCH v2] nvme: Look for StorageD3Enable on companion ACPI device instead

Adding Raul who has been asking for something like this as well.
I'd also really like to move nvme_acpi_storage_d3 out of the NVMe
driver. The Microsoft document that the original document references
makes it very clear that this is not NVMe specific, but also covers
at least AHCI. On top of that the platform simply can't know what kind
of PCIe device is in any given slot. Last but not least this will also
allow us to add quirks for devices that fail to properly mark this
misfeature in the ACPI tables.
