[PATCH v3] hwmon: (nct6683) Add customer ID for ASRock B650I Lightning WiFi

From: pklotz0

Date: Sat Apr 11 2026 - 20:17:49 EST


From: Petr Klotz <pklotz0@xxxxxxxxxxxxxx>

The ASRock B650I Lightning WiFi motherboard uses an NCT6686D chip with a
customer ID of 0x1633. Without this ID, the nct6683 driver fails to
recognize the hardware on this board, preventing hardware monitoring
from working.

Add NCT6683_CUSTOMER_ID_ASROCK6 (0x1633) to the list of supported customer
IDs and update the probe function to handle it
