Subject: [NETFILTER]: remove bogus memset() calls from ip_conntrack_netlink.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94cd2b67641e7ddc2e6ed71d76e00116957423db;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[NETFILTER]: remove bogus memset() calls from ip_conntrack_netlink.c

nfattr_parse_nested() calls nfattr_parse() which in turn does a memset
on the 'tb' array.  All callers therefore don't need to memset before
calling it.
