Would you happen to know what the error is in this case? I made sure I
was running the latest dtschema (v2023.9) and had yamllint installed as
well. When I took a look at the DTB and DTS output it looked ok...

usb-dai-link {
link-name = "USB Playback";
cpu {
sound-dai = <&q6afedai USB_RX>;//--->syntax error?
};

codec {
sound-dai = <&usbdai USB_RX>;
};

platform {
sound-dai = <&q6routing>;
};
};

I didn't make any changes to this in between v7 and v8, but v7 passed:

Thanks
