From 92a73e870478ddb2a2d137e3fff28828809bec2e Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Mon, 25 Jul 2016 20:47:17 +1200 Subject: lib/oe/recipeutils: fix patch_recipe*() with empty input If you supplied an empty file to patch_recipe() (or an empty list to patch_recipe_lines()) then the result was IndexError because the code checking to see if it needed to add an extra line of padding didn't check to see if there were in fact any lines before trying to access the last line. Fixes [YOCTO #9972].
