From: "Wang, Rui Y" <rui.y.wang@xxxxxxxxx> 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.
