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 problems:
- regression in new XTS/LRW code when used with async crypto
- long-standing bug in ahash API when used with certain algos
- bogus memory dereference in async algif_aead with certain algos"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: algif_aead - Fix bogus request dereference in completion function
crypto: ahash - Fix EINPROGRESS notification callback
crypto: lrw - Fix use-after-free on EINPROGRESS
crypto: xts - Fix use-after-free on EINPROGRESS
