From 4607ebf04b8190d2c7aa5504959e9fddfc0cd736 Mon Sep 17 00:00:00 2001 From: "Allan, Bruce W" Date: Tue, 7 Mar 2017 15:48:23 -0800 Subject: [PATCH] kbuild: external module build warnings when KBUILD_OUTPUT set and W=1 Commit db547ef19064 ("Kbuild: don't add obj tree in additional includes") causes warnings (-Wmissing-include-dirs) when compiling external modules with KBUILD_OUTPUT set and W=1. This is because $src can be an absolute path to the external module source which when prefixed with -I$(srctree)/ generates an incorrect directory path.
