From 14f92952bf74a365ca7f9dfbec158e7c933ea723 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 3 Jun 2010 19:37:27 -0700 Subject: [PATCH] ssb: add dma_dev to ssb_device structure Add dma_dev, a pointer to struct device, to struct ssb_device. We pass it to the generic DMA API with SSB_BUSTYPE_PCI and SSB_BUSTYPE_SSB. ssb_devices_register() sets up it properly. This is preparation for replacing the ssb bus specific DMA API (ssb_dma_*) with the generic DMA API.
