If the hardware advertises DMA support, the driver will expect DMA buffers to be passed in, but the USB core will not do this due to lack of a dma mask, breaking all connectiviy. To fix this, set a default dma_mask by pointing it at the coherent_dma_mask and set their value to a 32 bit mask. This still allows any platform code to set any more specific mask if needed, but makes the driver work for most dma-enabled hardware. It would be great if this patch could be included in 3.10, since it is needed to make the dwc2 driver work on the ralink rt3052 target. Before, the plan was to set up the dma mask in MIPS platform code, but because of a similar change in ehci and the uglyness of the code for that, the plan for that infrastructure was dropped. This patch makes the setting of the dma_mask happen in the same way as the patch Stephen Warren (set device dma_mask without reference to global data).
