Subject: [PATCH v6 07/23] drivers: crypto: meson: move algs definition and cipher API to cipher.c
Date: Tue, 26 Mar 2024 18:32:03 +0300 [thread overview]
Message-ID: <20240326153219.2915080-8-avromanov@salutedevices.com> (raw)
In-Reply-To: <20240326153219.2915080-1-avromanov@salutedevices.com>
Because that is proper place for them. In particular,
it takes less of exported symbol between compiling entities.
