From 567fd1d4a66a2d6e5599be0ada582e0a3dbd23d4 Mon Sep 17 00:00:00 2001 From: Qiang Liu Date: Thu, 9 Aug 2012 16:23:31 +0800 Subject: carma: remove unnecessary DMA_INTERRUPT capability These drivers set the DMA_INTERRUPT capability bit when requesting a DMA controller channel. This was historical, and is no longer needed. Recent changes to the drivers/dma/fsldma.c driver have removed support for this flag. This makes the carma drivers unable to find a DMA channel with the required capabilities. Cc: Arnd Bergmann Cc: Greg Kroah-Hartman Signed-off-by: Ira W.
