ASoC: Samsung: Generalize DMA driver namespace
Remove S3C,s3c from static defines. s3c_dma_ -> dma_ s3c24xx_runtime_ -> runtime_ s3c24xx_audio_ -> audio_ s3c_preallocate_ -> preallocate_ s3c24xx_soc_platform -> samsung_asoc_platform s3c24xx_pcm_driver -> asoc_dma_driver snd_s3c24xx_pcm_ -> samsung_asoc_ Signed-off-by: Jassi Brar <jassi.brar@samsung.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
