A variable to hold the streaming dma_mask, so that its in struct device rather than having to be separate. Yes, we can keep the pointer in there too, because that appears to convey meaning in the kernel today - whether the device can do DMA or not. A NULL dma_mask pointer already means it can't and dma_set_mask() always fails. A non-NULL dma_mask pointer means the driver can use dma_set_mask() to set an appropriate mask. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
