From 2a189f9e57650e9f310ddf4aad75d66c1233a064 Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Wed, 4 Nov 2015 14:47:53 +0100 Subject: [PATCH] ipv6: clean up dev_snmp6 proc entry when we fail to initialize inet6_dev 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.
