From cca1bbdd72f72a3cf86d90fd6f326fd709ae931f Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 2 Mar 2026 17:40:47 +0100 Subject: docs: kdoc_parser: don't mangle with function defines Mangling with #defines is not nice, as we may end removing the macro names, preventing several macros from being properly documented. Also, on defines, we have something like: #define foo(a1, a2, a3, ...) \ /* some real implementation */ The prototype part (first line on this example) won't contain any macros, so no need to apply any regexes on it. With that, move the apply_transforms() logic to ensure that it will be called only on functions.
