Are you talking about this message?
nvme nvme0: missing or invalid SUBNQN field
You can't do anything about it, but I wouldn't worry about it either.
If you want to see what the driver is reacting to, you can check the
subnqn from command line:
# nvme id-ctrl /dev/nvme0 | grep subnqn
It'll probably be all zeros. The field has been required by spec, but
the driver tolerates ones that don't implement it. It's just a message
that the device isn't spec compliant, but otherwise perfectly
operational.
