Christoph Hellwig 9d6a260bbf nvme: don't reject probe due to duplicate IDs for single-ported PCIe devices ... commit ac522fc6c3 upstream. While duplicate IDs are still very harmful, including the potential to easily see changing devices in /dev/disk/by-id, it turn out they are extremely common for cheap end user NVMe devices. Relax our check for them for so that it doesn't reject the probe on single-ported PCIe devices, but prints a big warning instead. In doubt we'd still like to see quirk entries to disable the potential for changing supposed stable device identifier links, but this will at least allow users how have two (or more) of these devices to use them without having to manually add a new PCI ID entry with the quirk through sysfs or by patching the kernel.
