From 472af2b05bdefcaee7e754e22cbf131110017ad6 Mon Sep 17 00:00:00 2001 From: Pawel Osciak Date: Mon, 14 Mar 2011 10:38:24 -0300 Subject: [media] videobuf2-dma-contig: make cookie() return a pointer to dma_addr_t dma_addr_t may not fit into void* on some architectures. To be safe, make vb2_dma_contig_cookie() return a pointer to dma_addr_t and dereference it in vb2_dma_contig_plane_paddr() back to dma_addr_t.
