Subject: Re: [PATCH 7/9] spi: s3c64xx: Use dma_request_chan() directly for
 channel request

Hi Peter,

I have a little concern here. We have two funcions
'dma_request_chan' and  'dma_request_channel' don't we end up
making some confusion here?

Wouldn't it make more sense renaming 'dma_request_chan' to
'dma_request_slave_channel_reason'?

Thanks,
Andi
