Do not select BACKLIGHT_CLASS_DEVICE from FB_BACKLIGHT. The latter only controls backlight support within fbdev core code and data structures. Make fbdev drivers depend on BACKLIGHT_CLASS_DEVICE and let users select it explicitly. Fixes warnings about recursive dependencies, such as error: recursive dependency detected! symbol BACKLIGHT_CLASS_DEVICE is selected by FB_BACKLIGHT symbol FB_BACKLIGHT is selected by FB_SH_MOBILE_LCDC symbol FB_SH_MOBILE_LCDC depends on FB_DEVICE symbol FB_DEVICE depends on FB_CORE symbol FB_CORE is selected by DRM_GEM_DMA_HELPER symbol DRM_GEM_DMA_HELPER is selected by DRM_PANEL_ILITEK_ILI9341 symbol DRM_PANEL_ILITEK_ILI9341 depends on BACKLIGHT_CLASS_DEVICE BACKLIGHT_CLASS_DEVICE is user-selectable, so making drivers adapt to it is the correct approach in any case. For most drivers, backlight support is also configurable separately. v3: - Select BACKLIGHT_CLASS_DEVICE in PowerMac defconfigs (Christophe) - Fix PMAC_BACKLIGHT module dependency corner cases (Christophe) v2: - s/BACKLIGHT_DEVICE_CLASS/BACKLIGHT_CLASS_DEVICE (Helge) - Fix fbdev driver-dependency corner case (Arnd) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Link: https://patchwork.freedesktop.org/patch/msgid/20241216074450.8590-2-tzimmermann@suse.de |
