From dc8d5f8de12146c8732d926a30e5f064d76061e0 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 16 May 2012 12:20:55 +0100 Subject: dmaengine: PL08x: get rid of unnecessary checks in dma_slave_config Get rid of the unnecessary checks in dma_slave_config utilizing the DMA direction. This allows us to move the computation of cctl to the prepare function.
