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"

Samsung SoC SSS (Security SubSystem) module
The SSS module in S5PV210 SoC supports the following:
-- Feeder (FeedCtrl)
-- Advanced Encryption Standard (AES)
-- Data Encryption Standard (DES)/3DES
-- Public Key Accelerator (PKA)
-- SHA-1/SHA-256/MD5/HMAC (SHA-1/SHA-256/MD5)/PRNG
-- PRNG: Pseudo Random Number Generator
The SSS module in Exynos4 (Exynos4210) and
Exynos5 (Exynos5420 and Exynos5250) SoCs
supports the following also:
-- ARCFOUR (ARC4)
-- True Random Number Generator (TRNG)
-- Secure Key Manager
Required properties:
- compatible : Should contain entries for this and backward compatible
SSS versions:
- "samsung,s5pv210-secss" for S5PV210 SoC.
- "samsung,exynos4210-secss" for Exynos4210, Exynos4212, Exynos4412, Exynos5250,
Exynos5260 and Exynos5420 SoCs.
- reg : Offset and length of the register set for the module
- interrupts : interrupt specifiers of SSS module interrupts, should contain
following entries:
- first : feed control interrupt (required for all variants),
- second : hash interrupt (required only for samsung,s5pv210-secss).
- clocks : list of clock phandle and specifier pairs for all clocks listed in
clock-names property.
- clock-names : list of device clock input names; should contain one entry
"secss".
