From 14c68c43b7695cbcfe148bf3c513b598c2886e7d Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 11 Oct 2017 10:53:28 +0100 Subject: [PATCH] net: mpls: make function ipgre_mpls_encap_hlen static The function ipgre_mpls_encap_hlen is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: symbol 'ipgre_mpls_encap_hlen' was not declared. Should it be static?
