Subject: swiotlb-xen: call xen_dma_sync_single_for_device when appropriate
From: Stefano Stabellini <[email protected]>
commit 9490c6c67e2f41760de8ece4e4f56f75f84ceb9e upstream.
In xen_swiotlb_sync_single we always call xen_dma_sync_single_for_cpu,
even when we should call xen_dma_sync_single_for_device. Fix that.
