Subject: [PATCH 1/3] kbuild: remove obj and src from the top Makefile
Date: Sat, 6 Jul 2019 12:07:11 +0900 [thread overview]
Message-ID: <20190706030713.6221-1-yamada.masahiro@socionext.com> (raw)
$(obj) is not used in the top Makefile at all. $(src) is used in
3 sites, but they can be replaced with $(srctree).
