parentcrypto: skcipher - fix crash in virtual walk (diff)
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: - a crash regression in the new skcipher walker - incorrect return value in public_key_verify_signature - fix for in-place signing in the sign-file utility" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: skcipher - fix crash in virtual walk sign-file: Fix inplace signing when src and dst names are both specified crypto: asymmetric_keys - set error code on failure
