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" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6: (60 commits) crypto: testmgr - add aead cbc des, des3_ede tests crypto: testmgr - Fix DMA-API warning crypto: cesa - tfm->__crt_alg->cra_type directly crypto: sahara - tfm->__crt_alg->cra_name directly crypto: padlock - tfm->__crt_alg->cra_name directly crypto: n2 - tfm->__crt_alg->cra_name directly crypto: dcp - tfm->__crt_alg->cra_name directly crypto: cesa - tfm->__crt_alg->cra_name directly crypto: ccp - tfm->__crt_alg->cra_name directly crypto: geode - Don't use tfm->__crt_alg->cra_name directly crypto: geode - Weed out printk() from probe() crypto: geode - Consistently use AES_KEYSIZE_128 crypto: geode - Kill AES_IV_LENGTH crypto: geode - Kill AES_MIN_BLOCK_SIZE crypto: mxs-dcp - Remove global mutex crypto: hash - Add real ahash walk interface hwrng: n2-drv - Introduce the use of the managed version of kzalloc crypto: caam - reinitialize keys_fit_inline for decrypt and givencrypt crypto: s5p-sss - fix multiplatform build hwrng: timeriomem - remove unnecessary OOM messages ...
