ASoC: Davinci: Fix race with cpu_dai->dma_data
This patch removes references to cpu_dai->dma_data. It makes struct davinci_pcm_dma_params part of struct davinci_mcbsp_dev or struct davinci_audio_dev. It removes the unused name variable from davinci_pcm_dma_params. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
