Subject: [PATCH v4 19/21] modpost: squash sym_update_namespace() into sym_add_exported()
Date: Sun, 14 May 2023 05:45:00 +0900	[thread overview]
Message-ID: <20230513204502.1593923-20-masahiroy@kernel.org> (raw)
In-Reply-To: <20230513204502.1593923-1-masahiroy@kernel.org>

Pass a set of the name, license, and namespace to sym_add_exported().

sym_update_namespace() is unneeded.
