Call vga_switcheroo_client_fb_set() with the PCI device from the instance of struct fb_info. All fbdev clients now run these calls. For non-PCI devices or drivers without vga-switcheroo, this does nothing. For i915 and radeon, it allows these drivers to use a common fbdev client. The device is the same as the one stored in struct drm_client and struct drm_fb_helper, so there is no difference in behavior. Some NULL-pointer checks are being removed, where those pointers cannot be NULL. v4: - clarify call semantics for drm_fb_helper_unregister_info() (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-3-tzimmermann@suse.de
