Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 

Pull crypto fixes from Herbert Xu:
 "This fixes a bug in the newly added Exynos5433 AES code as well as an
  old one in the caam driver"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: caam - add missing put_device() call
  crypto: s5p-sss - fix AES support for Exynos5433
