From 8bbb7cb2324d6a5fb7ccdc4ab0099dc18b91b690 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sun, 15 Nov 2015 09:00:42 +0100 Subject: [PATCH] batman-adv: Less checks in batadv_tvlv_unicast_send() * Let us return directly if a call of the batadv_orig_hash_find() function returned a null pointer. * Omit the initialisation for the variable "skb" at the beginning. * Replace an assignment by a call of the kfree_skb() function and delete the affected variable "ret" then.
