Pull crypto fixes from Herbert Xu:

 - Fix use after free in chtls

 - Fix RBP breakage in sha3

 - Fix use after free in hwrng_unregister

 - Fix overread in morus640

 - Move sleep out of kernel_neon in arm64/aes-blk

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  hwrng: core - Always drop the RNG in hwrng_unregister()
  crypto: morus640 - Fix out-of-bounds access
  crypto: don't optimize keccakf()
  crypto: arm64/aes-blk - fix and move skcipher_walk_done out of kernel_neon_begin, _end
  crypto: chtls - use after free in chtls_pt_recvmsg()
