[PATCH 2/5] hwmon: (nct6683) Add customer ID for ASRock B850 Steel Legend WiFi
From: Johan Dahlin
Date: Tue Aug 25 2026 - 05:27:00 EST
The ASRock B850 Steel Legend WiFi uses an NCT6686D chip reporting customer
ID 0x164a. Without this ID the driver refuses to probe unless the force
module parameter is set, leaving the board without hardware monitoring.
Add NCT6683_CUSTOMER_ID_ASROCK8 and handle it in the probe function.
