From 1353e576ae3b7b9703b74f6f2276b6dd450f4a2e Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 7 Jul 2022 09:05:46 +0100 Subject: crypto: x86/blowfish - remove redundant assignment to variable nytes Variable nbytes is being assigned a value that is never read, it is being re-assigned in the next statement in the while-loop. The assignment is redundant and can be removed. Cleans up clang scan-build warnings, e.g.: arch/x86/crypto/blowfish_glue.c:147:10: warning: Although the value stored to 'nbytes' is used in the enclosing expression, the value is never actually read from 'nbytes' Signed-off-by: Colin Ian King Signed-off-by: Herbert Xu --- arch/x86/crypto/blowfish_glue.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/x86/crypto') diff --git a/arch/x86/crypto/blowfish_glue.c b/arch/x86/crypto/blowfish_glue.c index ba06322c1e39..019c64c1340a 100644 --- a/arch/x86/crypto/blowfish_glue.c +++ b/arch/x86/crypto/blowfish_glue.c @@ -144,7 +144,7 @@ static int cbc_encrypt(struct skcipher_request *req) err = skcipher_walk_virt(&walk, req, false); - while ((nbytes = walk.nbytes)) { + while (walk.nbytes) { nbytes = __cbc_encrypt(ctx, &walk); err = skcipher_walk_done(&walk, nbytes); } @@ -225,7 +225,7 @@ static int cbc_decrypt(struct skcipher_request *req) err = skcipher_walk_virt(&walk, req, false); - while ((nbytes = walk.nbytes)) { + while (walk.nbytes) { nbytes = __cbc_decrypt(ctx, &walk); err = skcipher_walk_done(&walk, nbytes); } -- cgit v1.2.3
