Merge tag 'iommu-fixes-v3.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel: "Two small patches: * One patch to fix the function declarations for !CONFIG_IOMMU_API. This is causing build errors in linux-next and should be fixed for v3.6. * Another patch to fix an IOMMU group related NULL pointer dereference." * tag 'iommu-fixes-v3.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Fix wrong assumption in iommu-group specific code iommu: static inline iommu group stub functions
