From 79a0bffb835a094e523c448295d27ccbe6ac6a9b Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sun, 8 Aug 2021 19:11:08 +0200 Subject: batman-adv: Drop NULL check before dropping references The check if a batman-adv related object is NULL or not is now directly in the batadv_*_put functions. It is not needed anymore to perform this check outside these function: The changes were generated using a coccinelle semantic patch: @@ expression E; @@ - if (likely(E != NULL)) ( batadv_backbone_gw_put | batadv_claim_put | batadv_dat_entry_put | batadv_gw_node_put | batadv_hardif_neigh_put | batadv_hardif_put | batadv_nc_node_put | batadv_nc_path_put | batadv_neigh_ifinfo_put | batadv_neigh_node_put | batadv_orig_ifinfo_put | batadv_orig_node_put | batadv_orig_node_vlan_put | batadv_softif_vlan_put | batadv_tp_vars_put | batadv_tt_global_entry_put | batadv_tt_local_entry_put | batadv_tt_orig_list_entry_put | batadv_tt_req_node_put | batadv_tvlv_container_put | batadv_tvlv_handler_put )(E); Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich --- net/batman-adv/network-coding.c | 18 ++++++------------ 1 file changed, 6 insertions(+), 12 deletions(-) (limited to 'net/batman-adv/network-coding.c') diff --git a/net/batman-adv/network-coding.c b/net/batman-adv/network-coding.c index 136b1a8e5127..9f06132e007d 100644 --- a/net/batman-adv/network-coding.c +++ b/net/batman-adv/network-coding.c @@ -936,10 +936,8 @@ void batadv_nc_update_nc_node(struct batadv_priv *bat_priv, out_nc_node->last_seen = jiffies; out: - if (in_nc_node) - batadv_nc_node_put(in_nc_node); - if (out_nc_node) - batadv_nc_node_put(out_nc_node); + batadv_nc_node_put(in_nc_node); + batadv_nc_node_put(out_nc_node); } /** @@ -1215,14 +1213,10 @@ static bool batadv_nc_code_packets(struct batadv_priv *bat_priv, batadv_send_unicast_skb(skb_dest, first_dest); res = true; out: - if (router_neigh) - batadv_neigh_node_put(router_neigh); - if (router_coding) - batadv_neigh_node_put(router_coding); - if (router_neigh_ifinfo) - batadv_neigh_ifinfo_put(router_neigh_ifinfo); - if (router_coding_ifinfo) - batadv_neigh_ifinfo_put(router_coding_ifinfo); + batadv_neigh_node_put(router_neigh); + batadv_neigh_node_put(router_coding); + batadv_neigh_ifinfo_put(router_neigh_ifinfo); + batadv_neigh_ifinfo_put(router_coding_ifinfo); return res; } -- cgit v1.2.3
