[PATCH] nvme-pci: add quirk for Wodposit WPBSNM8-256GTP to disable secondary temp thresholds
Posted by Ilikara Zheng 1 week, 3 days ago 
Secondary temperature thresholds (temp2_{min,max}) were not reported
properly on this NVMe SSD. This resulted in an error while attempting to
read these values with sensors(1):

  ERROR: Can't get value of subfeature temp2_min: I/O error
  ERROR: Can't get value of subfeature temp2_max: I/O error

Add the device to the nvme_id_table with the
NVME_QUIRK_NO_SECONDARY_TEMP_THRESH flag to suppress access to all non-
composite temperature thresholds.

I'm not finding vendor 1FA0 registered on the public pci-ids, nor in the
pcisig.com members list. I just want to make sure the identifier is
officially registered.

When I run command lspci -vvnnk, I got outputs below:

I have no idea why they didn't use their PCI Vendor ID, see 
https://pcisig.com/membership/member-companies where they used a 
different Vendor ID (0x2094).

I have tested this patch on a CTCISZ 3B6000M-NUC with an exact same SSD 
and this has resolved the error with sensor(1).
