Subject[PATCH 3.12 045/142] crypto: cryptd - Assign statesize properly
Date
From: "Wang, Rui Y" <rui.y.wang@intel.com>

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

===============

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.
