Subject: [PATCH 4/5] kbuild: rename subdir-obj-y to subdir-builtin
Date: Fri, 22 May 2020 11:00:01 +0900 [thread overview]
Message-ID: <20200522020002.504506-4-masahiroy@kernel.org> (raw)
In-Reply-To: <20200522020002.504506-1-masahiroy@kernel.org>
I think subdir-builtin is clearer.
While I was here, I made its build rule explicit.
