hwmon (nct6775): Please fix Invalid temperature source error for NCT6798D

[Stefan Dietrich <roots@gmx.de>]

Hi all,

with my Asus Formula XII Z490 and 5.7.0-7.1-liquorix-amd64 I'm getting
the following error messages during boot:

nct6775: Found NCT6798D or compatible chip at 0x2e:0x290
nct6775 nct6775.656: Invalid temperature source 28 at index 0, source
register 0x100, temp register 0x73

register 0x200, temp register 0x75
nct6775 nct6775.656: Invalid temperature source 28 at index 2, source

nct6775 nct6775.656: Invalid temperature source 28 at index 5, source
register 0xa00, temp register 0x7d

During sensors-detect, most of the standard temperature, voltage and
rpm sources are recognized, however, some of the values, particularly
voltages, are off quite a bit. In addition, output of additional
temperature sensors (via headers on the mainboard) which are reported
fine in BIOS, are missing.

Booting with acpi_enforce_resources=lax doesn't solve this issue.

I'd be happy if anyone would be able to fix this issue or give any
pointers on how to do so. Unfortunately I only have very basic coding
skills, but I'll be happy to assist in debugging.


Cheers,
Stefan
