Subject: dma-mapping: fix the prototype of dma_map_single()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c22c0dbd7d3bb7ce47779b757d567d2e7746744b;p=u-boot.git

dma-mapping: fix the prototype of dma_map_single()

Make dma_map_single() return the dma address, and remove the
pointless volatile.
