Partially works with MSI B650M MORTAR WIFI

[flippette]

Hi, thank you for your work. I have the B650M MORTAR WIFI with an NCT8867R I/O controller (found in manual).

I see this when the module is loaded:

Jun 05 14:00:37 okinawa kernel: nct6687: Found NCT6687D or compatible chip at 0x004e:>
Jun 05 14:00:37 okinawa kernel: nct6687 nct6687.2592: NCT6687D EC firmware version 0.>
Jun 05 14:00:37 okinawa systemd-modules-load[547]: Inserted module 'nct6687'

This is what sensors outputs:

M2_1, CPU 1P8 and CPU VDDP doesn't seem to work, PCIe x1 seems really high to me (is it?), this board doesn't have fan headers 4-6.

My hardware:

• MSI B650M MORTAR WIFI
• Ryzen 9 7950X
• Both M.2 slots have SSDs
• All fan headers on the board are used
• I don't know what PCIe x1 is referring to, this board only goes down to a x4 slot

The PCIe x1 temperature has been abnormally high on some boards for a while, not an issue with this particular kernel module https://www.reddit.com/r/buildapc/comments/101upqu/pcie_x1_temperature_abnormally_high/

On this motherboard I get errors:

@vladns You may need to blacklist the nct6683 module.
