From e26ffb31dfa30d498b963a86d231835e3af7d3df Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Fri, 3 Nov 2017 10:59:00 +0100 Subject: [PATCH] build: fix module symbol collection if build_dir is a symlink If PKG_BUILD_DIR contains symlinks, the generated Module.symvers will contain the resolved paths, not the virtual path with the symlink name. This breaks the filter for the module's own symbols, so to fix this ensure we also grep for the resolved path.
