drivers/nvme: Add quirks for device 126f:2262
[ Upstream commit e89086c43f
]
This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for
device [126f:2262], which appears to be a generic VID:PID pair used for
many SSDs based on the Silicon Motion SM2262/SM2262EN controller.
Two of my SSDs with this VID:PID pair exhibit the same behavior:
* They frequently have trouble exiting the deepest power state (5),
resulting in the entire disk unresponsive.
Verified by setting nvme_core.default_ps_max_latency_us=10000 and
observing them behaving normally.
* They produce all-zero nguid and eui64 with `nvme id-ns` command.
The offending products are:
* HP SSD EX950 1TB
* HIKVISION C2000Pro 2TB
