drm: ensure drm headers are self-contained and pass kernel-doc Ensure drm headers build, are self-contained, have header guards, and have no kernel-doc warnings, when CONFIG_DRM_HEADER_TEST=y. The mechanism follows similar patters used in i915, xe, and usr/include. To cover include/drm, we need to recurse there using the top level Kbuild and the new include/Kbuild files. v4: check for CONFIG_WERROR in addition to CONFIG_DRM_WERROR v3: adapt to upstream build changes v2: make DRM_HEADER_TEST depend on DRM Suggested-by: Daniel Vetter <daniel@ffwll.ch> Cc: David Airlie <airlied@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Simona Vetter <simona.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/d8ad1c6d707f38a55987f616cb9650aef30b84e1.1737556766.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com> 2025-01-22 16:41:34 +02:00
