Subject: [DCCP]: Call dccp_feat_init more early in dccp_v4_init_sock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=04e2661e9c00386412b64612549cf24c8baef67c;p=linux-beck.git

[DCCP]: Call dccp_feat_init more early in dccp_v4_init_sock

So that dccp_feat_clean doesn't get confused with uninitialized
list_heads.

Noticed when testing with no ccid kernel modules.
