ASoC: soc-generic-dmaengine: Handle DMA channel request failures correctly
Currently any dma_request_chan() failure other than -EPROBE_DEFER is
silently ignored, since a missing channel is expected for devices that
only support one DMA direction.
Improve the handling of these failures by:
- reporting failures when a configured DMA channel cannot be requested;
- failing probe if neither playback nor capture obtains a DMA channel,
since the PCM device would be unusable.
Devices that legitimately support only one DMA direction continue to
work as before.
