Subject: [PATCH 3.18 117/145] crypto: cryptd - Assign statesize properly

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

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

From: Wang, Rui Y <rui.y.wang@...el.com>

commit 1a07834024dfca5c4bed5de8f8714306e0a11836 upstream.

cryptd_create_hash() fails by returning -EINVAL.  It is because after
8996eafdc ("crypto: ahash - ensure statesize is non-zero") all ahash
drivers must have a non-zero statesize.

This patch fixes the problem by properly assigning the statesize.
