Hi all,

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

net/bridge/br_nf_core.c:77:1: error: expected identifier or '(' before '{' token
 {
 ^
net/bridge/br_nf_core.c:88:12: error: redefinition of 'br_nf_core_init'

            ^

                    ^

Caused by commit 34666d467cbf ("netfilter: bridge: move br_netfilter
out of the core").  This build has CONFIG_BRIDGE_NETFILTER not set ...

I have applied the following patch for today:
