Erwan Le Ray 01ce9c5d17 serial: stm32: fix FIFO flush in startup and set_termios ... [ Upstream commit 315e2d8a125ad77a1bc28f621162713f3e7aef48 ] Fifo flush set USART_RQR register by calling stm32_usart_set_bits routine (Read/Modify/Write). USART_RQR register is a write only register. So, read before write isn't correct / relevant to flush the FIFOs. Replace stm32_usart_set_bits call by writel_relaxed.
