Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

   - Crash in caam hash due to uninitialised buffer lengths.

   - Alignment issue in caam RNG that may lead to non-random output"

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: caam - fix RNG buffer cache alignment
  crypto: caam - improve initalization for context state saves
