Subject: [PATCH] kbuild: do not create built-in objects for external module builds
Date: Wed, 9 Sep 2020 05:55:57 +0900 [thread overview]
Message-ID: <20200908205557.2746352-1-masahiroy@kernel.org> (raw)
'make M=/path/to/your/external/module' creates a pointless built-in.a
in the top of the external module directory because KBUILD_BUILTIN is
set to 1.
Clear KBUILD_BUILTIN when we are building external modules so that
'make M=...' and 'make M=... modules' work equivalently.
