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 ?
