[Qemu-devel] [RFC v0 4/8] object: create default canonical paths for orphans

[Peter A. G. Crosthwaite]

Create a default canonical path for an object which doesnt have one. This
is a workaround for a bug probably buried deep with qdev as objects should
always have valid canonical paths, but the need came about with the
petalogix_ml605_mmu platform, the ethernet and dma devices as created by
qdev have bogus paths (apparently).
