Re: [PATCH v7 18/22] dma-direct: select DMA address encoding from __DMA_ATTR_ALLOC_CC_SHARED

Also in: linux-arm-kernel, linux-coco, linux-iommu, linux-s390, lkml

-	*dma_handle = phys_to_dma_direct(dev, page_to_phys(page));
+	*dma_handle = phys_to_dma_direct(dev, page_to_phys(page),
+					 !!(attrs & __DMA_ATTR_ALLOC_CC_SHARED));

The !! isn't needed when going through bool, the compiler does it
automatically.
