From f2281d42f6edb5934406cc1d32fa982e05b2ed41 Mon Sep 17 00:00:00 2001 From: Christian Eggers Date: Mon, 29 Jul 2013 20:54:09 +0200 Subject: [PATCH] spi: spi-davinci: Fix direction in dma_map_single() commit 89c66ee890af18500fa4598db300cc07c267f900 upstream. Commit 048177ce3b3962852fd34a7e04938959271c7e70 (spi: spi-davinci: convert to DMA engine API) introduced a regression: dma_map_single() is called with direction DMA_FROM_DEVICE for rx and for tx.
