The requirement is dual licensed and matching patterns: * Schemas: /GPL-2\.0(?:-only)? OR BSD-2-Clause/ * Headers: /GPL-2\.0(?:-only)? OR \S+/ Above patterns suggested by Rob at: https://lore.kernel.org/all/CAL_Jsq+-YJsBO+LuPJ=ZQ=eb-monrwzuCppvReH+af7hYZzNaQ@xxxxxxxxxxxxxx The issue was found during patch review: https://lore.kernel.org/all/20230313201259.19998-4-ddrokosov@xxxxxxxxxxxxxx/ Link: https://lkml.kernel.org/r/20230404191715.7319-1-ddrokosov@xxxxxxxxxxxxxx Signed-off-by: Dmitry Rokosov <ddrokosov@xxxxxxxxxxxxxx> Reviewed-by: Rob Herring <robh@xxxxxxxxxx> Cc: Andy Whitcroft <apw@xxxxxxxxxxxxx> Cc: Dwaipayan Ray <dwaipayanray1@xxxxxxxxx> Cc: Joe Perches <joe@xxxxxxxxxxx> Cc: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Cc: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- scripts/checkpatch.pl | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) --- a/scripts/checkpatch.pl~checkpatch-introduce-proper-bindings-license-check +++ a/scripts/checkpatch.pl @@ -3763,7 +3763,7 @@ sub process { "'$spdx_license' is not supported in LICENSES/...\n" . $herecurr); } if ($realfile =~ m@^Documentation/devicetree/bindings/@ && - not $spdx_license =~ /GPL-2\.0.*BSD-2-Clause/) { + $spdx_license !~ /GPL-2\.0(?:-only)?
