Jiri Kosina 4bf3631cdb 8250: fix possible deadlock between serial8250_handle_port() and serial8250_interrupt() ... Commit 40b36daa introduced possibility that serial8250_backup_timeout() -> serial8250_handle_port() locks port.lock without disabling irqs, thus allowing deadlock against interrupt handler (port.lock is acquired in serial8250_interrupt()).
