stable inclusion from linux-4.19.203 commit 08882fba72a9be9446d744c60d6d418f547a0c96
--------------------------------
[ 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.
