  cros_ec_spi.c:153: warning: Function parameter or member 'ec_dev' not described in 'receive_n_bytes'
  cros_ec_spi.c:153: warning: Function parameter or member 'buf' not described in 'receive_n_bytes'
  cros_ec_spi.c:153: warning: Function parameter or member 'n' not described in 'receive_n_bytes'
