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

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

   - memory corruption when kmalloc fails in xts/lrw

   - mark some CCP DMA channels as private

   - fix reordering race in padata

   - regression in omap-rng DT description"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: xts,lrw - fix out-of-bounds write after kmalloc failure
  crypto: ccp - Make some CCP DMA channels private
  padata: avoid race in reordering
  dt-bindings: rng: clocks property on omap_rng not always mandatory
