This patch fixes the issue that when buffer allocation is requested without iommu, the allocation is failed. Without iommu, dma_alloc_attrs function allocates some memory region and returns cpu address so this patch makes the cpu address to be set to buf->kvaddr correctly. Changelog v2: - fix buffer free . Without iommu, dma_free_attrs function requires kernel space address as argument. So it changes the argument, buf->pages to buf->kvaddr.
