swiotlb: search and replace "int dir" with "enum dma_data_direction dir"
.. to catch anybody doing something funky. See "swiotlb: swiotlb: add swiotlb_tbl_map_single library function" for full description of patchset. [v2: swiotlb_sync_single_range_* no more - removed usage] [v3: enum dma_data_direction direction -> enum dma_data_direction dir] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Tested-by: Albert Herranz <albert_herranz@yahoo.es>
