Missing or invalid SUBNQN on Corsair MP600 1TB device

[Claus Stovgaard]

Hi

This is my first post to this mailing list, so please forgive me if it
is already discussed.

I have just build a new workstation, where I noticed the following
warning for the Corsair MP600 1 TB drive.

nvme nvme0: missing or invalid SUBNQN field.

it arrived with firmware 11.3 and I have later upgraded to firmware
13.0 to see if they have fixed the firmware.

Have also reported in their forum
https://forum.corsair.com/forums/showthread.php?p=1077109#post1077109

Looking in the host pci.c code it seems to be a known issue on some
drives where the "NVME_QUIRK_IGNORE_DEV_SUBNQN" is used.

So I guess that Corsair MP600 is a candidate for the same quirk.

Considered to add the Corsair to the list of drives with
NVME_QUIRK_IGNORE_DEV_SUBNQN, but would just ask here first, if it
would be the correct use and understanding.

Regards Claus

Below is info for my system for reference.
