Subject[PATCH 4.10 26/62] ipv6: sr: fix double free of skb after handling invalid SRH
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Lebrun <david.lebrun@uclouvain.be>


[ Upstream commit 95b9b88d2da5e43e025400afcb492643933bf858 ]

The icmpv6_param_prob() function already does a kfree_skb(),
this patch removes the duplicate one.

Fixes: 1ababeba4a21f3dba3da3523c670b207fb2feb62 ("ipv6: implement dataplane support for rthdr type 4 (Segment Routing Header)")
