Subject: AMD IOMMU: remove now unnecessary #ifdefs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=065a6d68c71af2a3bdd080fa5aa353b76eede8f5;p=linux-beck.git

AMD IOMMU: remove now unnecessary #ifdefs

The #ifdef's are no longer necessary when the iommu-api and the amd
iommu updates are merged together.
