The type is never restored, and hda_bus_match() requires the device and driver types to be equal. After unbinding the codec driver via sysfs the HDA_DEV_LEGACY codec drivers no longer match the device and bind fails with -ENODEV. Restore HDA_DEV_LEGACY with a device managed action registered before the component, so it runs after the component and the card are gone.
