[Qemu-devel] [PATCH] virtio-gpu: update console device property.

[Qemu-devel] [PATCH] virtio-gpu: update console device property.

[Gerd Hoffmann]

Update the device link of the QemuConsole, so it points to the
virtio-gpu-pci or virtio-vga device instead of virtio-gpu-device.

This is needed because we want to find the device by id, for
example for input routing, and the id specified on the command
line is attached to the pci proxy, not the virtio device.
