From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> 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.
