Valentin Caron 82a99bc85c serial: stm32: prevent TDR register overwrite when sending x_char ... [ Upstream commit d3d079bde0 ] When sending x_char in stm32_usart_transmit_chars(), driver can overwrite the value of TDR register by the value of x_char. If this happens, the previous value that was present in TDR register will not be sent through uart. This code checks if the previous value in TDR register is sent before writing the x_char value into register.
