From 15177608c703e7b4aa29aa7c93b31001effe504c Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Tue, 29 Oct 2013 00:37:37 +0000 Subject: [PATCH] swiotlb-xen: fix error code returned by xen_swiotlb_map_sg_attrs map_sg returns the number of elements mapped, not a dma_addr_t. In case of error return 0, not DMA_ERROR_CODE.
