commit ce385dd8221b35541533241cc6134d4b99694b56

    device: Add scan_generic_bus support
    
    scan_smbus routine does not perform any smbus specific operation. Thus,
    rename the routine to scan_generic_bus so that it can be used by other
    buses like SPI. Add a wrapper scan_smbus to allow other users of smbus
    scan to continue working as before.
