From 4451d494b1910bf7b7f8381a637d0fe6d2142467 Mon Sep 17 00:00:00 2001 From: Cristian Stoica Date: Thu, 14 Aug 2014 13:51:57 +0300 Subject: [PATCH] crypto: caam - fix addressing of struct member buf_0 and buf_1 in caam_hash_state are not next to each other. Accessing buf_1 is incorrect from &buf_0 with an offset of only size_of(buf_0). The same issue is also with buflen_0 and buflen_1 Cc: # 3.13+ Signed-off-by: Cristian Stoica Signed-off-by: Herbert Xu --- drivers/crypto/caam/caamhash.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/crypto/caam/caamhash.c b/drivers/crypto/caam/caamhash.c index 061f3fbd9c79..f347ab7eea95 100644 --- a/drivers/crypto/caam/caamhash.c +++ b/drivers/crypto/caam/caamhash.c @@ -1417,9 +1417,9 @@ static int ahash_update_first(struct ahash_request *req) struct device *jrdev = ctx->jrdev; gfp_t flags = (req->base.flags & (CRYPTO_TFM_REQ_MAY_BACKLOG | CRYPTO_TFM_REQ_MAY_SLEEP)) ?
