From a45ee8ed0c7df7d459e8134feac9a5287dc9e9c6 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Tue, 3 Aug 2021 12:00:16 +0200 Subject: [PATCH] net: ipv6: fix returned variable type in ip6_skb_dst_mtu [ Upstream commit 4039146777a91e1576da2bf38e0d8a1061a1ae47 ] The patch fixing the returned value of ip6_skb_dst_mtu (int -> unsigned int) was rebased between its initial review and the version applied. In the meantime fade56410c22 was applied, which added a new variable (int) used as the returned value. This lead to a mismatch between the function prototype and the variable used as the return value.
