    Subject[PATCH AUTOSEL 5.10 38/51] nvme-pci: mark Samsung PM1725a as IGNORE_DEV_SUBNQN
    Date
    From: Gopal Tiwari <gtiwari@redhat.com>

    [ Upstream commit 7ee5c78ca3895d44e918c38332921983ed678be0 ]

    A system with more than one of these SSDs will only have one usable.
    Hence the kernel fails to detect nvme devices due to duplicate cntlids.

    [ 6.274554] nvme nvme1: Duplicate cntlid 33 with nvme0, rejecting
    [ 6.274566] nvme nvme1: Removing after probe failure status: -22

    Adding the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk to resolves the issue.
