Today's next tree fails to build on s390 with following errors.

arch/s390/crypto/sha1_s390.c:67: error: 'struct sha1_state' has no member named 'buf'
arch/s390/crypto/sha1_s390.c:68: error: 'struct sha1_state' has no member named 'func'

arch/s390/crypto/sha256_s390.c:64: error: 'struct sha256_state' has no member named 'func'

Probably because of commit 406f104b4172de7452702c6810807c1b0132ba22.

In sha1_/sha256_import() functions struct s390_sha_ctx *sctx should be
used instead of struct sha1_state.

The following patch fixed the issue for me.

Thanks
