[PATCH v4 1/1] USB: ch341: set tty baud speed according to tty struct

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 t
