From 6124c04c1344497e0cbfb505ddbd3b83090a4d51 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 6 Sep 2017 16:19:05 -0700 Subject: modpost: simplify sec_name() There is code duplication between sec_name() and sech_name(). Simplify sec_name() by re-using sech_name(). Also, move them up to remove the forward declaration of sec_name().
