From b2ea189a958a6129e484fa8e583d91878913c50f Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 15 Feb 2025 08:57:51 +0800 Subject: [PATCH] crypto: skcipher - Zap type in crypto_alloc_sync_skcipher [ Upstream commit ee509efc74ddbc59bb5d6fd6e050f9ef25f74bff ] The type needs to be zeroed as otherwise the user could use it to allocate an asynchronous sync skcipher.
