iommu/amd: Initialize device table after dma_ops When dma_ops are initialized the unity mappings are created. The init_device_table_dma() function makes sure DMA from all devices is blocked by default. This opens a short window in time where DMA to unity mapped regions is blocked by the IOMMU. Make sure this does not happen by initializing the device table after dma_ops. Cc: stable@vger.kernel.org Signed-off-by: Joerg Roedel <joro@8bytes.org>
