Subject: [PATCH 5/5] crypto: octeontx2 - use memcpy_and_pad() in aead_hmac_init()
Date: Mon, 21 Sep 2026 08:11:24 +0200 [thread overview]
Message-ID: <20260921061120.29694-10-blum@kernel.org> (raw)
In-Reply-To: <20260921061120.29694-6-blum@kernel.org>
Use memcpy_and_pad() instead of separate memcpy() and memset() calls to
simplify aead_hmac_init().
Signed-off-by: Thorsten Blum <blum@kernel.org>
