[ Upstream commit 2a189f9e ] In ipv6_add_dev, when addrconf_sysctl_register fails, we do not clean up the dev_snmp6 entry that we have already registered for this device. Call snmp6_unregister_dev in this case. Fixes: a317a2f1 ("ipv6: fail early when creating netdev named all or default") Reported-by: Dmitry Vyukov <dvyukov@google.com> Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.
