From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Allow rproc serial ports to receive data before the port is connected. Rproc serial ports usually talk to very simple remote devices with no control queue managing open/close events. So we must let remote devices write to the virtio ring even if the device is not yet fully initialized. Signed-off-by: Sjur Br?ndeland
