| |
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang, Rui Y <rui.y.wang@intel.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.
