Research direction
Start by tracing temperature reporting for the mt7615e driver and MT7663BEN from /sys/class/ieee80211/phy1/hwmon0/temp1_input, using the device/uevent details to confirm the PCI device. Compare the current sensor path with the driver's hardware-monitoring behavior. Done means the sensor reports the card temperature instead of 0.
