Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes a NULL pointer dereference on allocation failure in caam,
as well as a regression in the ctr mode on s390 that was added with
the recent concurrency fixes"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: s390 - fix aes,des ctr mode concurrency finding.
crypto: caam - add allocation failure handling in SPRINTFCAT macro
