Hi Andy and Joe,


I met a Checkpatch warning issue for ath12k wifi node:


./scripts/checkpatch.pl arch/arm64/boot/dts/qcom/sm8750-mtp.dts
WARNING: DT compatible string vendor "pci17cb" appears un-documented -- 
check ./Documentation/devicetree/bindings/vendor-prefixes.yaml#1026: 
FILE: arch/arm64/boot/dts/qcom/sm8750-mtp.dts:1026:
+               compatible = "pci17cb,1107";

total: 0 errors, 1 warnings, 1275 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
       mechanically convert to the typical style using --fix or 
--fix-inplace.

arch/arm64/boot/dts/qcom/sm8750-mtp.dts has style problems, please review.

NOTE: If any of the errors are false positives, please report
       them to the maintainer, see CHECKPATCH in MAINTAINERS.


All dts files which contain (compatible = "pci17cb,1107"; ) met this 
warning. But in fact this DT compatible string is already defined in  
devicetree/bindings/net/wireless/qcom,ath12k.yaml

I raised a new change review 
https://lore.kernel.org/all/20251210032817.1264850-1-yingying.tang@oss.qualcomm.com, 
it also met this issue.


Could please help to resolve this issue, thanks very much
