ASoC: samsung: pass DMA channels as pointers
ARM64 allmodconfig produces a bunch of warnings when building the samsung ASoC code: sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data': sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] playback_data->filter_data = (void *)playback->channel; sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] capture_data->filter_data = (void *)capture->channel; We could easily shut up the warning by adding an intermediate cast, but there is a bigger underlying problem: The use of IORESOURCE_DMA to pass data from platform code to device drivers is dubious to start with, as what we really want is a pointer that can be passed into a filter function. Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.
