From ec8b5e48c03790a68cb875fe5064007a9cbdfdd0 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 14 Sep 2012 15:05:47 +0300 Subject: dmaengine: Pass flags via device_prep_dma_cyclic() callback Change the parameter list of device_prep_dma_cyclic() so the DMA drivers can receive the flags coming from clients. This feature can be used during audio operation to disable all audio related interrupts when the DMA_PREP_INTERRUPT is cleared from the flags.
