I have just build a new workstation, where I noticed the following

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

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.

Yes, that is the correct quirk to use with devices reporting spec
revision 1.2.1 compatibility but are not compliant with the subsys nqn
field. The device should continue to work without the quirk, but you'll
get the warning.
