Uwe Kleine-König ea2624b5b8 serial: stm32: Reset .throttled state in .startup() ... When an UART is opened that still has .throttled set from a previous open, the RX interrupt is enabled but the irq handler doesn't consider it. This easily results in a stuck irq with the effect to occupy the CPU in a tight loop. So reset the throttle state in .startup() to ensure that RX irqs are handled.
