Currently the hdmi i2s playback stream and hdmi spdif playback stream
are using the same name. So when they are enabled at the same time,
kernel will print this warning:
[    2.201835] hdmi-audio-codec hdmi-audio-codec.1.auto: ASoC: Failed to
create Playback debugfs file
Assign different names to them to avoid that.
