From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 23 Oct 2020 15:27:48 -0700 Subject: [PATCH] crypto: x86/poly1305 - add back a needed assignment commit c3a98c3ad5c0dc60a1ac66bf91147a3f39cac96b upstream. One of the assignments that was removed by commit 4a0c1de64bf9 ("crypto: x86/poly1305 - Remove assignments with no effect") is actually needed, since it affects the return value. This fixes the following crypto self-test failure: alg: shash: poly1305-simd test failed (wrong result) on test vector 2, cfg="init+update+final aligned buffer" Fixes: 4a0c1de64bf9 ("crypto: x86/poly1305 - Remove assignments with no effect") Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu Signed-off-by: Jason A.
