[alsa-devel] [PATCH] s3c24xx-pcm: fix hw_params dma handling

Hi,

While testing the recently merged driver for the neo1973, I found out that it was not working due to dma allocation failure. The problem is that there's only one dma channel available on s3c2410 and there may be more than one call to pcm_ops->hw_params(), resulting in dma request failures. This patch from Harald Welte fix this.
