From 4b2ce9ddb370c4eb573540611c347d78ac4b54a0 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 20 Jan 2011 05:50:36 +0800 Subject: [PATCH] dmaengine: imx-sdma: set sdmac->status to DMA_ERROR in err_out of sdma_prep_slave_sg() sdma_prep_dma_cyclic() sets sdmac->status to DMA_ERROR in err_out, and sdma_prep_slave_sg() needs to do the same. Otherwise, sdmac->status stays at DMA_IN_PROGRESS, which will make the function return immediately next time it gets called.
