fbdev: Handle video= parameter in video/cmdline.c Handle the command-line parameter video= in video/cmdline.c. Implement the fbdev helper fb_get_options() on top. Will allows to handle the kernel parameter in DRM without fbdev dependencies. Note that __video_get_options() has the meaning of its return value inverted compared to fb_get_options(). The new helper returns true if the adapter has been enabled, and false otherwise. There is the ofonly parameter, which disables output for non-OF-based framebuffers. It is only for offb and looks like a workaround. The actual purpose it not clear to me. Use 'video=off' or 'nomodeset' instead.

video/cmdline: Hide __video_get_options() behind CONFIG_FB_CORE The function __video_get_options() only exists for compatibility with old fbdev drivers that cannot be refactored easily. Hide it behind CONFIG_FB_CORE. v2: * support CONFIG_FB_CORE=m via IS_ENABLED() (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20240118090721.7995-3-tzimmermann@suse.de
