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:
