Subject: [PATCH] crypto: atmel-ecc - drop dead code in atmel_ecdh_max_size

From: Thorsten Blum <[email-masked]>
Date: Wed, 3 Jun 2026 00:25:19 +0200

atmel_ecdh_init_tfm() always allocates ctx->fallback, so it is never
NULL in atmel_ecdh_max_size(). Remove the dead code and return
crypto_kpp_maxsize() directly.
