8fc38062 - fbdev: Fix recursive dependencies wrt BACKLIGHT_CLASS_DEVICE

Mon, 16 Dec 2024 07:42:47 +0000

fbdev: Fix recursive dependencies wrt BACKLIGHT_CLASS_DEVICEDo not select BACKLIGHT_CLASS_DEVICE from FB_BACKLIGHT. The latteronly controls backlight support within fbdev core code and datastructures.Make fbdev drivers depend on BACKLIGHT_CLASS_DEVICE and let usersselect it explicitly. Fixes warnings about recursive dependencies,such aserror: 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_DEVICEBACKLIGHT_CLASS_DEVICE is user-selectable, so making drivers adapt toit is the correct approach in any case.
