- * A note on resource allocation:
- *
- * All drivers needing DMA channels, should allocate and release them
- * through the public routines `request_dma()' and `free_dma()'.
- *
- * In order to avoid problems, all processes should allocate resources in
- * the same sequence and release them in the reverse order.
- *
- * So, when allocating DMAs and IRQs, first allocate the DMA, then the IRQ.
- * When releasing them, first release the IRQ, then release the DMA. The
- * main reason for this order is that, if you are requesting the DMA buffer
- * done interrupt, you won't know the irq number until the DMA channel is
- * returned from request_dma.
