Thanks for your answer. I have the latest Dell bios installed (which
applied quite some firmware updates as well during install -- not that
I remembered which one exactly) and officially this device is too old
for support from Dell.

I didn't see any recents hits with google for this error, so maybe
it's just this device. I guess I can add a `return 0;`  just before
the `nvme_ctrl_limited_cns` call in `nvme_init_non_mdts_limits`
locally for now.
