From 9b941c6660bae673e27c207f1d20d98ef8ecd450 Mon Sep 17 00:00:00 2001 From: Zhang Wei <wei.zhang@freescale.com> Date: Thu, 13 Mar 2008 17:45:28 -0700 Subject: [PATCH] dmaengine: Fix a bug about BUG_ON() on DMA engine capability DMA_INTERRUPT. The device->device_prep_dma_interrupt function is used by DMA_INTERRUPT capability, not DMA_ZERO_SUM.
