[alsa-devel] [PATCH 08/18] ASoC: Samsung: Generalize DMA driver namespace

26 Oct 2010

From: Jassi Brar jassi.brar@samsung.com
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_
