I'm still worried about this.
If power state based suspend does always work despite a HMB and is
preferred for the specific Google board we should have purely a DMI
based quirk for the board independent of the NVMe controller used with
it.
But if these LiteON devices can't properly handle nvme_de

LiteON(SSSTC) CL1 device running FW 220TQ,22001 has bugs with simple
suspend.
When NVMe device receive D3hot from host, NVMe firmware will do
garbage collection. While NVMe device do Garbage collection,
firmware has chance to going incorrect address.
In that case, NVMe storage device goes to no de
