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. For most drivers, backlightsupport 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 Reviewed-by: Arnd Bergmann Link: https://patchwork.freedesktop.org/patch/msgid/20241216074450.8590-2-tzimmermann@suse.de List of files: /linux-6.15/drivers/video/fbdev/Kconfig

fbdev: sstfb: Make CONFIG_FB_DEVICE optionalThe sstfb driver currently depends on CONFIG_FB_DEVICE to create sysfsentries and access info->dev. This patch wraps the relevant code blockswith #ifdef CONFIG_FB_DEVICE, allowing the driver to be built and usedeven if CONFIG_FB_DEVICE is not selected.The sysfs setting only controls the VGA pass-through state and is notrequired for the display to work correctly.(See: http://vogonswiki.com/index.php/VGA_passthrough_cablefor more information.)Added some fixes from Thomas Zimmermann.Signed-off-by: Gonzalo Silvalde Blanco Signed-off-by: Thomas Zimmermann Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller List of files: /linux-6.15/drivers/video/fbdev/Kconfig

689237ab - fbdev/intelfb: Remove driver

Fri, 05 Jan 2024 09:10:36 +0000

fbdev/intelfb: Remove driverFrom looking at the PCI IDs, every device supported by intelfb isalso supported by i915. Anyone still using intelfb should pleasemove on to i915, which does everything intelfb does but better.Removing intelfb is motivated by the driver's excessive use of theglobal screen_info state. The state belongs to architecture andfirmware code; device drivers should not attempt to access it. Butfixing intelfb would require a significant change in the driver'sprobing logic. As intelfb has been obsolete for nearly 2 decades,it is probably not worth the effort. Let's just remove it.
