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

Pull crypto fixes from Herbert Xu:

 - Fix missed wake-up race in padata

 - Use crypto_memneq in ccp

 - Fix version check in ccp

 - Fix fuzz test failure in ccp

 - Fix potential double free in crypto4xx

 - Fix compile warning in stm32

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  padata: use smp_mb in padata_reorder to avoid orphaned padata jobs
  crypto: ccp - Fix SEV_VERSION_GREATER_OR_EQUAL
  crypto: ccp/gcm - use const time tag comparison.
  crypto: ccp - memset structure fields to zero before reuse
  crypto: crypto4xx - fix a potential double free in ppc4xx_trng_probe
  crypto: stm32/hash - Fix incorrect printk modifier for size_t
