The following line confuses the style checker. I assume this is related to the patch context, as I cannot reproduce the issue without that specific patch. PassRefPtr<CustomFilterParameter> StyleResolver::parseCustomFilterTransformParameter(const String& name, CSSValueList* values) https://bugs.webkit.org/show_bug.cgi?id=71401#c8 Failed to run "['Tools/Scripts/check-webkit-style', '--diff-files', u'LayoutTests/ChangeLog', u'LayoutTests/css3..." exit_code: 1 Source/WebCore/css/StyleResolver.cpp:5264: Local variables should never be PassRefPtr (see http://webkit.org/coding/RefPtr.html).

PassRefPtr is deprecated, and this style check will be removed soon.
