Subject: [PATCH] hwmon: (nct6775) Accept PECI Calibration as temperature source for NCT6798D
Git-commit: 8a03746c8baf82e1616f05a1a716d34378dcf780
Patch-mainline: v5.8-rc6
References: git-fixes
Stefan Dietrich reports invalid temperature source messages on Asus Formula
XII Z490.
nct6775 nct6775.656: Invalid temperature source 28 at index 0,
source register 0x100, temp register 0x73
Debugging suggests that temperature source 28 reports the CPU temperature.
Let's assume that temperature sources 28 and 29 reflect "PECI Agent {0,1}
Calibration", similar to other chips of the series.
