Jose Abreu 6fce983f9b ASoC: dwc: Fix PIO mode initialization ... We can no longer rely on the return value of devm_snd_dmaengine_pcm_register(...) to check if the DMA handle is declared in the DT. Previously this check activated PIO mode but currently dma_request_chan returns either a valid channel or -EPROBE_DEFER. In order to activate PIO mode check instead if the interrupt line is declared. This reflects better what is documented in the DT bindings (see Documentation/devicetree/bindings/sound/ designware-i2s.txt). Also, initialize use_pio variable which was never being set causing PIO mode to never work.
