If UART is runtime PM enabled and using DMA, the DMA completion will leave
device powered on. Fix it by calling serial8250_rpm_put_tx() in DMA completion
callback.
Changes v2:

Andy Shevchenko (2):
serial: 8250_port: export serial8250_rpm_{get|put}_tx()
serial: 8250_dma: power off device after TX is done
