From ba7fcb0c954921534707f08ebc4d8beeb2eb17e7 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Mon, 29 Aug 2011 03:20:56 -0300 Subject: [PATCH] [media] media: vb2: dma contig allocator: use dma_addr instread of paddr Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested that this is the physical address in system memory. For most ARM platforms these two are the same, but this is not a generic rule. 'dma_addr' will also point better to dma-mapping api.
