[ 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

[ Upstream commit ab35ad950d439ec3409509835d229b3d93d3c7f9 ]
Add two quirks for the WDC Blue SN550 (PCI ID 15b7:5009) based on user
reports and hardware analysis:
- NVME_QUIRK_NO_DEEPEST_PS:
liaozw talked to me the problem and solved with
nvme_core.default_ps_max_latency_us=0, so add the quirk.
I also found some reports in the following link.
- NVME_QUIRK_BROKEN_MSI:
after get the lspci from Jack Rio.
I think that the disk also have NVME_QUIRK_BROKEN_MSI.
described in commit d5887dc6b6c0 ("nvme-pci: Add quirk for broken MSIs")
as sean said in link which match the MSI 1/32 and MSI-X 17.

[ Upstream commit 46d22b47df2741996af277a2838b95f130436c13 ]
queue->state_change is set as part of nvmet_tcp_set_queue_sock(), but if
the TCP connection isn't established when nvmet_tcp_set_queue_sock() is
called then queue->state_change isn't set and sock->sk->sk_state_change
isn't replaced.
As such we don't need to restore sock->sk->sk_state_change if
queue->state_change is NULL.
This avoids NULL pointer dereferences such as this:
