- case (~DMA_D0 & ~DMA_D1):
- pr_debug("DMA %d empty irq.\n", stream->dma);
This case should return IRQ_NONE really since it didn't handle an interrupt...
If that last case ever happens the DMA engine is broken, as it shouldn't issue interrupts when no transfer is in progress. The errata sheets don't mention anything (yet).
In that case this should be an error rather than debug level print and I'd say the IRQ_NONE thing definitely applies. -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
