When running kernel-doc over multiple documents, it emits
one error message per file with is not what we want:
$ python3.6 scripts/kernel-doc.py . --none
...
Warning: ./include/trace/events/swiotlb.h:0 Python 3.7 or later is required for correct results
Warning: ./include/trace/events/iommu.h:0 Python 3.7 or later is required for correct results
Warning: ./include/trace/events/sock.h:0 Python 3.7 or later is required for correct results
...
Change the logic to warn it only once at the library:
$ python3.6 scripts/kernel-doc.py . --none
Warning: Python 3.7 or later is required for correct results
Warning: ./include/cxl/features.h:0 Python 3.7 or later is required for correct results
When running from command line, it warns twice, but that sounds
ok.
