The ch341_set_baudrate() function initialize the device baud speed according to the value on priv->baud_rate. By default the ch341_open() set it to a hardcoded value (DEFAULT_BAUD_RATE 9600). Unfortunately, the tty_struct is not initialized with the same default value. (usually 56700) This means that the tty_struct and the device baud rate generator are not synchronized after opening the port. Fixup is done by calling ch341_set_termios() if tty exist. Remove unnecessary variable priv->baud_rate setup as it's already done by ch341_port_probe(). Remove unnecessary call to ch341_set_{handshake,baudrate}() in ch341_open() as there already called in ch341_configure() and ch341_set_termios() Signed-off-by: Nicolas PLANEL Signed-off-by: Johan Hovold Signed-off-by: Ben Hutchings --- Reading git-diff-tree failed
