#1279355 — [PATCH 0/2] crypto: Fix driver load failure

ghash_clmulni_intel fails to load on Linux 4.3+ with the following message:
"modprobe: ERROR: could not insert 'ghash_clmulni_intel': Invalid argument"

These two patches need to go together, for the driver to load correctly.

Rui Wang (2):
  crypto: ghash-clmulni - Fix load failure
  crypto: cryptd - Assign statesize properly

#1279357 — [PATCH 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.
