Subject: [PATCH 2/2] kconfig: remove dead code in conf_askvalue()
Date: Sun, 21 Feb 2021 18:26:23 +0900 [thread overview]
Message-ID: <20210221092623.133572-2-masahiroy@kernel.org> (raw)
In-Reply-To: <20210221092623.133572-1-masahiroy@kernel.org>
conf_askvalue() is only called for oldconfig, syncconfig, and
oldaskconfig. If it is called for other cases, it is a bug.
So, the code after the switch statement is unreachable.
Remove the dead code, and clean up the switch statement.
