If anyone has any objections, please let me know. ------------------ From: Sabrina Dubroca [ Upstream commit 2a189f9e57650e9f310ddf4aad75d66c1233a064 ] 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.
