Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
- Fix build error in crypto lib code when crypto API is off
- Fix NULL/error check in hisilicon
- Fix Kconfig-related build error in talitos
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: hisilicon - fix a NULL vs IS_ERR() bug in sec_create_qp_ctx()
crypto: talitos - Fix build error by selecting LIB_DES
crypto: arch - conditionalize crypto api in arch glue for lib code
