History
Ilpo Järvinen 197eb5c416 serial: 8250_dw: Use serial_lsr_in() in dw8250_handle_irq() 
dw8250_handle_irq() reads LSR under a few conditions, convert both to
use serial_lsr_in() in order to preserve LSR flags properly across
reads.

Fixes: 424d79183a ("serial: 8250_dw: Avoid "too much work" from bogus rx timeout interrupt")
Fixes: aa63d786ce ("serial: 8250: dw: Add support for DMA flow controlling devices")
