CONFIG_OF vs DMA_OF

[Kuninori Morimoto]

Hi Vinod

${LINUX}/drivers/dma/of-dma.c will be compiled if .config has DMA_OF

	obj-$(CONFIG_DMA_OF) += of-dma.o

But, ${LINUX}/include/linux/of_dma.h is based on CONFIG_OF

	#ifdef CONFIG_OF
	extern int of_dma_controller_register(struct device_node *np,
	...
	#else
	static inline int of_dma_controller_register(struct device_node *np,
	...
	#endif

I have issue if .config has CONFIG_OF but not have DMA_OF.
Is this correct patch ?
