From 70fd646ae5ddaae0a7fbbba94b500bde2e1211f0 Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Wed, 3 Jun 2026 00:25:19 +0200 Subject: [PATCH] crypto: atmel-ecc - drop dead code in atmel_ecdh_max_size 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.
