Subject: [PATCH] crypto: marvell/cesa - use memcpy_and_pad in mv_cesa_ahash_export
Date: Tue, 17 Mar 2026 17:52:57 +0100 [thread overview]
Message-ID: <20260317165258.1304521-2-thorsten.blum@linux.dev> (raw)
Replace memset() followed by memcpy() with memcpy_and_pad() to simplify
the code and to write to 'cache' only once.
