Replaced snd_soc_register_platform with devm_snd_soc_register_platform in samsung_asoc_dma_platform_register(). This makes the function samsung_asoc_dma_platform_unregister() redundant. This is removed and all its users are updated. Signed-off-by: Tushar Behera <tushar.behera@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
