It also cleans up the DRM bridge debugfs code by moving code to drm_bridge.c. Luca Signed-off-by: Luca Ceresoli --- Changes in v8: - moved more code to drm_bridge.c, which makes adding '#if CONFIG_DEBUG_FS' unnecessary - a small fix to a harmless bug - Link to v7: https://lore.kernel.org/r/20250225-drm-debugfs-show-all-bridges-v7-0-8826037ada37@bootlin.com This series was initially part of v6 of this other series: - Link to v6: https://lore.kernel.org/dri-devel/20250206-hotplug-drm-bridge-v6-0-9d6f2c9c3058@bootlin.com/ --- Luca Ceresoli (2): drm/bridge: move bridges_show logic from drm_debugfs.c drm/debugfs: add top-level 'bridges' file showing all added bridges drivers/gpu/drm/drm_bridge.c | 70 +++++++++++++++++++++++++++++++++++++++++++ drivers/gpu/drm/drm_debugfs.c | 38 +---------------------- drivers/gpu/drm/drm_drv.c | 2 ++ include/drm/drm_bridge.h | 3 ++ 4 files changed, 76 insertions(+), 37 deletions(-) --- base-commit: b439ab75b6382f5c34aec6e87435cf7e58e72a35 change-id: 20250225-drm-debugfs-show-all-bridges-642e870b71e7 Best regards, -- Luca Ceresoli
