crypto: mv_cesa - fix hashing of chunks > 1920 bytes (27425286) · Commits · 戴 / test

This was broken by commit (yes, myself). The basic problem here is since the digest state is only saved after the last chunk, the state array is only valid when handling the first chunk of the next buffer. Broken since linux-3.0. Signed-off-by:
