 drivers/spi/spi-topcliff-pch.c:184: warning: Function parameter or member 'pkt_tx_buff' not described in 'pch_spi_data'
 drivers/spi/spi-topcliff-pch.c:184: warning: Function parameter or member 'pkt_rx_buff' not described in 'pch_spi_data'
 drivers/spi/spi-topcliff-pch.c:184: warning: Function parameter or member 'dma' not described in 'pch_spi_data'
 drivers/spi/spi-topcliff-pch.c:184: warning: Function parameter or member 'use_dma' not described in 'pch_spi_data'
 drivers/spi/spi-topcliff-pch.c:184: warning: Function parameter or member 'save_total_len' not described in 'pch_spi_data'
