Here, fixed it for you:

    setup_spi(
      &adc,
      mode        = SPI_01,
      rate        = 15,
      cs_control  = CS_MUXED,
      cs          = 0x01 );
    setup_spoo(
      &adc,
      mode        = SPI_01,
      rate        = 15,
      cs_control  = CS_MUXED,
      cs          = 0x01 );
    setup_s(
      &adc,
      mode        = SPI_01,
      rate        = 15,
      cs_control  = CS_MUXED,
      cs          = 0x01 );
    validate_and_register_spi_spoo_s(
      &adc,
      mode        = SPI_01,
      rate        = 15,
      cs_control  = CS_MUXED,
      cs          = 0x01 );
