sound: oxygen: handle cards with missing EEPROM
The card model detection code introduced in 2.6.30 that tries to work around partially broken EEPROM contents by reading the EEPROM directly does not handle cards where the EEPROM has been omitted. In this case, we have to use the default ID to allow the driver to load.
