From c19bdf24cc274e96006267173d664df2ef4b13db Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sun, 2 Nov 2025 15:42:05 -0800 Subject: [PATCH] lib/crypto: x86/blake2s: Drop check for nblocks == 0 Since blake2s_compress() is always passed nblocks != 0, remove the unnecessary check for nblocks == 0 from blake2s_compress_ssse3(). Note that this makes it consistent with blake2s_compress_avx512() in the same file as well as the arm32 blake2s_compress().
