Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

net/sched/cls_api.c: In function 'tc_dump_tfilter':
net/sched/cls_api.c:1362:8: warning: 'parent' may be used uninitialized in this function [-Wmaybe-uninitialized]
   if (!tcf_chain_dump(chain, q, parent, skb, cb,
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         index_start, &index))
         ~~~~~~~~~~~~~~~~~~~~

Probably introduced by commit

  7960d1daf278 ("net: sched: use block index as a handle instead of qdisc when block is shared")
