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: <stable@vger.kernel.org> # 3.13+ Signed-off-by: Cristian Stoica <cristian.stoica@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
