Subject: [PATCH v2 4/8] crypto/qat: fix size calculation for memset
Date: Wed, 13 Nov 2024 17:52:18 -0800	[thread overview]
Message-ID: <20241114015405.77060-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20241114015405.77060-1-stephen@networkplumber.org>

The memset was always doing 0 bytes since size computed later.

Link: https://pvs-studio.com/en/blog/posts/cpp/1179/

Fixes: 3a80d7fb2ecd ("crypto/qat: support SHA3 plain hash")
Cc: stable@dpdk.org
