Subject: ppc/pnv: Loop on the whole hierarchy to populate the DT with the XSCOM nodes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=109dce37860aeb0e8894cb36b29d40f279c6bb6b;p=qemu.git

ppc/pnv: Loop on the whole hierarchy to populate the DT with the XSCOM nodes

Some PnvXScomInterface objects lie a bit deeper (PnvPBCQState) than
the first layer, so we need to loop on the whole object hierarchy to
catch them.
