From 450d87eaeb4d43bd9e1f9523a6a3bfeb48209fea Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 21 Jan 2008 16:42:42 +1100 Subject: [PATCH] [POWERPC] Add celleb_dma_dev_setup() Celleb always uses dma_direct_ops, and sets dma_direct_offset, so it too should set dma_data to dma_direct_offset. Currently there's no pci_dma_dev_setup() routine for Celleb so add one.
