All of these source files do #include <sound/core.h>,
but these missing/implicit functions are conditional:

#ifdef CONFIG_ISA_DMA_API
#define DMA_MODE_NO_ENABLE	0x0100

void snd_dma_program(unsigned long dma, unsigned long addr, unsigned int size, unsigned short mode);
void snd_dma_disable(unsigned long dma);
unsigned int snd_dma_pointer(unsigned long dma, unsigned int size);
#endif

so should these drivers all depend on ISA_DMA_API ?
or should only pieces of each driver depend on ISA_DMA_API ?
