[Qemu-devel] [PATCH qemu v2 2/2] object: Handle objects with no parents

[Alexey Kardashevskiy <aik@ozlabs.ru>]

At the moment object_get_canonical_path_component() crashes on assert()
if the object does not have a parent. Usually it is not called for
orphan objects but various HMP/QMP commands can do that (info mtree,
qom-get).

This adds few more tests in object_get_canonical_path() to prevent QEMU
from crashing.
