When using virtio-console on s390, the input doesn't work. The root of the problem is rather simple. What happens is the following: 1) create character device for stdio 2) char device is done creating, sends OPENED event 3) virtio-console adds handlers 4) no event comes because the char device is open already 5) virtio-console doesn't accept input because it didn't receive an OPENED event To make that sure virtio-console gets notified that the character device is open even when it's been open from the beginning, this patch introduces a variable that keeps track of the opened state. If the device is open when the event handlers get installed, we just notify the handler. This fixes input with virtio-console on s390.
