Subject: [PATCH 07/13] kconfig: move conf_set_all_new_symbols() to conf.c
Date: Sun, 14 Mar 2021 04:48:30 +0900 [thread overview]
Message-ID: <20210313194836.372585-7-masahiroy@kernel.org> (raw)
In-Reply-To: <20210313194836.372585-1-masahiroy@kernel.org>
This function is only used in conf.c. Move it there together with the
randomize_choice_values() helper.
