Subject: swiotlb: Drop unused functions swiotlb_map_sg and swiotlb_unmap_sg
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ebcf6f979d55f35dfe36956364f0dce8c738220b;p=openwrt%2Fstaging%2Fblogic.git

swiotlb: Drop unused functions swiotlb_map_sg and swiotlb_unmap_sg

There are no users for swiotlb_map_sg or swiotlb_unmap_sg so we might as
well just drop them.
