[PATCH 5.10 085/152] nvme-pci: mark Samsung PM1725a as IGNORE_DEV_SUBNQN

[Greg Kroah-Hartman]

From: Gopal Tiwari <gtiwari@xxxxxxxxxx>

[ 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.
