Hi Geert, Greg, Arnd,

Any ideas about these build errors?

Only a few arches define DMA_AUTOINIT:

$ grep -w DMA_AUTOINIT arch/*/include/asm/dma*.h
arch/alpha/include/asm/dma.h:#define DMA_AUTOINIT	0x10
arch/arm/include/asm/dma.h:#define DMA_AUTOINIT	 0x10
arch/mips/include/asm/dma.h:#define DMA_AUTOINIT	0x10
arch/parisc/include/asm/dma.h:#define DMA_AUTOINIT	0x10
arch/powerpc/include/asm/dma.h:#define DMA_AUTOINIT		0x10
arch/sh/include/asm/dma.h:#define DMA_AUTOINIT		0x10
arch/x86/include/asm/dma.h:#define DMA_AUTOINIT		0x10


CONFIG_ISA_DMA_API=y
but CONFIG_ISA is not set.
(Yes, this is ColdFire.)

menuconfig SND_ISA
	bool "ISA sound devices"
	depends on ISA || COMPILE_TEST
	depends on ISA_DMA_API
	default y

I suppose that we could drop the "|| COMPILE_TEST" part.


thanks.
