spear_pcm_request_chan() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the SPEAr DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().
