Subject: [PATCH net-next] ipv6: remove unnecessary local variable
Date: Thu, 15 Jul 2021 22:26:43 +0800	[thread overview]
Message-ID: <20210715142643.2648-1-rocco.yue@mediatek.com> (raw)

The local variable "struct net *net" in the two functions of
inet6_rtm_getaddr() and inet6_dump_addr() are actually useless,
so remove them.
