Subject: crypto: caam - fix addressing of struct member
From: Cristian Stoica <cristian.stoica@xxxxxxxxxxxxx>
commit 4451d494b1910bf7b7f8381a637d0fe6d2142467 upstream.
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
