Subject: [PATCH AUTOSEL 6.6 07/12] nvme-pci: add quirks for device 126f:1001

From: Wentao Guan <guanwentao@...ontech.com>

[ Upstream commit 5b960f92ac3e5b4d7f60a506a6b6735eead1da01 ]

This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for
device [126f:1001].

It is similar to commit e89086c43f05 ("drivers/nvme: Add quirks for
device 126f:2262")

Diff is according the dmesg, use NVME_QUIRK_IGNORE_DEV_SUBNQN.

dmesg | grep -i nvme0:
  nvme nvme0: pci function 0000:01:00.0
  nvme nvme0: missing or invalid SUBNQN field.
  nvme nvme0: 12/0/0 default/read/poll queues
