+QEMU fails with duplicate SaveStateEntry when using two legacy virtio input devices
+Description of problem:
+QEMU bails out when it is started with two virtio-input devices running in legacy virtio mode, using two different transports (like PCI and CCW on s390x).
+Steps to reproduce:
+```
+qemu-system-s390x -M s390-ccw-virtio-2.6 -cpu max -nographic -device virtio-multitouch-pci -device virtio-tablet-ccw
+```
+fails with:
+```
+qemu-system-s390x: -device virtio-tablet-ccw: savevm_state_handler_insert: Detected duplicate SaveStateEntry: id=virtio-input, instance_id=0x0
+```
+Additional information:
+The problem does *not* occur if using modern virtio devices (which automatically happens for -M s390-ccw-virtio-2.7 and newer) or if using virtio-input devices with the same transport (e.g. two PCI devices instead of one PCI and one CCW).
+
+Also note that the problem only occurs since QEMU 8.1 since older versions did not check for duplicate SaveStateEntries (see commit caa91b3c44cdb2d2921e25 ).
