[PATCH v3 1/2] nvme-pci: Print error message on failure in nvme_probe

[Gerd Bayer]

Add a new error message that makes failures to probe visible in the
kernel log, like:
nvme 0008:00:00.0: error -ENODEV: probe failed

This highlights issues with a particular device right away instead of
leaving users to search for missing drives.
