Set the firmware framebuffer's parent device, which usually is the graphics hardware's physical device. Integrates the framebuffer in the Linux device hierarchy and lets Linux handle dependencies among devices. For example, the graphics hardware won't be suspended while the firmware device is still active. v4: * fix build for CONFIG_SYSFB_SIMPLEFB=n, again v3: * fix build for CONFIG_SYSFB_SIMPLEFB=n (Sui) * test result of screen_info_pci_dev() for errors (Sui) v2: * detect parent device in sysfb_parent_dev() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-4-tzimmermann@suse.de
