    ssb: Fix usage of struct device used for DMAing · 4ac58469

    This fixes DMA on architectures where DMA is nontrivial, like PPC64.
    We must use the host-device's (PCI) struct device for any DMA
    operation instead of the SSB device. For this we add a new
    struct device pointer to the SSB device structure that will always
    point to the right device for DMAing.
    
    Without this patch b43 and b44 drivers won't work on complex-DMA
    architectures, that for example need dev->archdata for DMA operations.
