[Qemu-devel] [PATCH v3 08/17] hw/arm/fsl-imx6: Fix introspection problems with the "fsl, imx6" device |

Running QEMU with valgrind indicates a problem here:
echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
"'arguments':{'typename':'fsl,imx6'}}" \
"{'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" | \
valgrind -q aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio
[...]
==32417== Invalid read of size 8
==32417== at 0x618A7A: qdev_print (qdev-monitor.c:686)

==32417== by 0x452B38: handle_hmp_command (monitor.c:3446)
[...]
Use the new sysbus_init_child_obj() and object_initialize_child() to make
sure that the objects are removed correctly when the parent gets destroyed.
