[PATCH 2/6] spi: loopback-test: don't skip comparing the first byte of rx_buf

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When the loopback parameter is set, rx_buf are compared with tx_buf
after the spi_message is executed.  But the first byte of buffer is
not checked.
