From: Stephen Warren swarren@nvidia.com

struct snd_dmaengine_pcm_config's new chan_names field implements the same feature, and nothing uses SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME, so remove it.

Signed-off-by: Stephen Warren swarren@nvidia.com --- This follows on from the patch "ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_config" which I posted earlier today.
