c6x: include: asm: dma-mapping: Add dummy dma_sync_single_range_for_device
c6x does not implement get_dma_ops() for dma-mapping-common.h. And in dma-mapping-common.h, dma_sync_single_range_for_device() may be dummy. So c6x can just define a dummy function for allmodconfig building. CC [M] drivers/net/ethernet/micrel/ks8851.o drivers/net/ethernet/micrel/ks8842.c: In function 'ks8842_tx_frame_dma': drivers/net/ethernet/micrel/ks8842.c:453:2: error: implicit declaration of function 'dma_sync_single_range_for_device' [-Werror=implicit-function-declaration] dma_sync_single_range_for_device(adapter->dev, ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Mark Salter <msalter@redhat.com>
