Subject: [PATCH 4.3 010/200] crypto: sun4i-ss - add missing statesize

4.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: LABBE Corentin <clabbe.montjoie@...il.com>

commit 4f9ea86604e3ba64edd2817795798168fbb3c1a6 upstream.

sun4i-ss implementaton of md5/sha1 is via ahash algorithms.
Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
made impossible to load them without giving statesize. This patch
specifiy statesize for sha1 and md5.

Fixes: 6298e948215f ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator")
