sctp: fix a missed .data initialization
As commit 3c68198e75111a90("sctp: Make hmac algorithm selection for cookie generation dynamic"), we miss the .data initialization. If we don't use the net_namespace, the problem that parts of the sysctl configuration won't be isolation and won't occur. In sctp_sysctl_net_register(), we register the sysctl for each net, in the for(), we use the 'table[i].data' as check condition, so when the 'i' is the index of sctp_hmac_alg, the data is NULL, then break. So add the .data initialization. Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Wang Weidong <wangweidong1@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
