Gustavo wants to access the QOM path of an input IRQ line
from the NVIC, but since the device is orphan he ends up
with this nasty path [*]:

  -device ivshmem-flat,chardev=ivshmem_flat,x-irq-qompath='/machine/unattached/device[1]/nvic/unnamed-gpio-in[0]',x-bus-qompath='/sysbus'

Add the missing parent so the tree is now:

(qemu) info qom-tree
/machine (lm3s6965evb-machine)
  /gamepad (stellaris-gamepad)
  /oled (ssd0323)
  /peripheral (container)
  /peripheral-anon (container)
  /soc (container)
    /v7m (armv7m)
      /cpu (cortex-m3-arm-cpu)
        /unnamed-gpio-in[0] (irq)
        /unnamed-gpio-in[1] (irq)
        /unnamed-gpio-in[2] (irq)
        /unnamed-gpio-in[3] (irq)
      /cpuclk (clock)
      /nvic (armv7m_nvic)
        /NMI[0] (irq)
        /nvic_sysregs[0] (memory-region)
        /systick-trigger[0] (irq)
        /systick-trigger[1] (irq)
        /unnamed-gpio-in[0] (irq)
        ...
