Subject: [PATCH] crypto: atmel-tdes - use min3 to simplify sg_copy and crypt_start
Date: Mon, 25 May 2026 11:29:27 +0200 [thread overview]
Message-ID: <20260525092927.818586-2-thorsten.blum@linux.dev> (raw)
Replace multiple min() and min_t() calls with min3() to simplify the
code. Using min3() instead of min_t() in atmel_tdes_crypt_start() is
safe since the values are all unsigned and compatible.
