Subject: [PATCH] nvme-pci: add NVME_QUIRK_BOGUS_NID for Samsung PM9B1 256G and
512G
The Samsung PM9B1 512G SSD found in some Lenovo Yoga 7 14ARB7 laptop units
reports eui as 0001000200030004 when resuming from s2idle, causing the
device to be removed with this error in dmesg:
nvme nvme0: identifiers changed for nsid 1
To fix this, add a quirk to ignore namespace identifiers for this device.
