Hi Hanns

Bisect shows it was introduced with this commit.

    nvme: rework NVME_AUTH Kconfig selection

    Having a single Kconfig symbol NVME_AUTH conflates the selection
    of the authentication functions from nvme/common and nvme/host,
    causing kbuild robot to complain when building the nvme target
    only. So introduce a Kconfig symbol NVME_HOST_AUTH for the nvme
    host bits and use NVME_AUTH for the common functions only.
    And move the CRYPTO selection into nvme/common to make it
    easier to read.
