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
