Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6 into next

Pull crypto updates from Herbert Xu:
 "Here is the crypto update for 3.16:

   - Added test vectors for SHA/AES-CCM/DES-CBC/3DES-CBC.
   - Fixed a number of error-path memory leaks in tcrypt.
   - Fixed error-path memory leak in caam.
   - Removed unnecessary global mutex from mxs-dcp.
   - Added ahash walk interface that can actually be asynchronous.
   - Cleaned up caam error reporting.
   - Allow crypto_user get operation to be used by non-root users.
   - Add support for SSS module on Exynos.
   - Misc fixes"
