Subject: crypto: cryptd - Assign statesize properly
X-Git-Tag: v4.1.12-93~3^2~2

crypto: cryptd - Assign statesize properly

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.
