serial: stm32: add RX and TX FIFO flush Adds a flush of RX and TX FIFOs, and fixes some errors: - adds RX FIFO flush in startup fonction - removes the useless transmitter enabling in startup fonction (e.g. receiver only, see Documentation/serial/driver) - configures FIFO threshold before enabling it, rather than after - flushes both TX and RX in set_termios function Signed-off-by: Erwan Le Ray <erwan.leray@st.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
