[alsa-devel] davinci_request_dma()

I'm looking for a little bit more help reading the SOC code. In particular, I'm reading davinci-pcm.c, and function davinci_pcm_dma_request, which makes two calls to davinci_request_dma. However, when I grep for davinci_request_dma, the only places I can find it are in davinci_pcm_dma_request itself!

[jkacur@mydcore linux-2.6.26]$ grep -rn davinci_request_dma * sound/soc/davinci/davinci-pcm.c:143: ret = davinci_request_dma(prtd->params->channel, prtd->params->name, sound/soc/davinci/davinci-pcm.c:150: ret = davinci_request_dma(PARAM_ANY, "Link",

Either I'm missing something, or this code wouldn't even compile. I would appreciate any help in understanding this.

Thank you.
