Subject: [PATCH 8/8] kbuild: support modules_sign for external modules as well
Date: Wed, 23 Aug 2023 20:50:48 +0900	[thread overview]
Message-ID: <20230823115048.823011-8-masahiroy@kernel.org> (raw)
In-Reply-To: <20230823115048.823011-1-masahiroy@kernel.org>

The modules_sign target is currently only available for in-tree modules,
but it actually works for external modules as well.

Move the modules_sign rule to the common part.
