From 258aea76f552cc755da92e7e823abbb85e021514 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 1 Feb 2012 16:12:19 +0530 Subject: dmaengine: Pass dma_slave_config .device_fc = NULL for all existing users .device_fc is added in struct dma_slave_config recently. All user drivers, which want DMA to be the flow controller must pass this field as false. As earlier driver don't look to use this feature, mark it false for now.
