ARM: SAMSUNG: DMA Cleanup as per sparse
Function declaration differs between file: dma.c and file:dma.h and SPARSE (Documentation/sparse.txt) gives error messages All dma channels are members of 'enum dma_ch' and not 'unsigned int' Please have a look at channel definitions in: arch/arm/mach-s3c64xx/include/mach/dma.h arch/arm/plat-samsung/include/plat/s3c-dma-pl330.h arch/arm/mach-s3c2410/include/mach/dma.h So all arguments should be of type 'enum dma_ch' Signed-off-by: Sangwook Lee <sangwook.lee@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
