Use the existing dma_chan_name() helper to obtain the per-channel device name instead of open-coding: dev_name(chan->dev->device) / dev_name(chan2dev()) Simplify the code and improve consistency. No functional change intended....quoted
ret = devm_request_irq(dev, lchan->irq, loongson2_cmc_dma_chan_irq, IRQF_SHARED, - dev_name(chan2dev(lchan)), lchan); + dma_chan_name(&lchan->vchan.chan), lchan);Depending on the amount of users (and I expect there is a number), I would expect specific API for virt-dma case.
Make sense, I consider it before. Let's wait for while for patch2's comments Frank
