Re: [alsa-devel] [PATCH v2 04/15] dmaengine: Pass no_wakeup parameter via device_prep_dma_cyclic() callback

Change the parameter list of device_prep_dma_cyclic() so the DMA drivers can receive the no_wakeup request coming from client drivers. This feature can be used during audio operation to disable all audio related interrupts.

We already have a flag to indicate this, see * @DMA_PREP_INTERRUPT - trigger an interrupt (callback) upon completion of * this transaction

Unfortunately, the addition of cyclic API missed having this flag. So right way would be to add flag argument in the API.
