From c60ac31542e93499b58dcfc1e3f6550ba5b5728e Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 19 Feb 2013 13:25:46 +0000 Subject: metag: Provide dma_get_sgtable() metag/allmodconfig: drivers/media/v4l2-core/videobuf2-dma-contig.c: In function 'vb2_dc_get_base_sgt': drivers/media/v4l2-core/videobuf2-dma-contig.c:387: error: implicit declaration of function 'dma_get_sgtable' For architectures using dma_map_ops, dma_get_sgtable() is provided in . Metag does not use dma_map_ops yet, hence it should implement it as an inline stub using dma_common_get_sgtable().
