firmware/sysfb: Disable sysfb for firmware buffers with unknown parentdrm-misc-fixes-2024-09-26
The sysfb framebuffer handling only operates on graphics devices
that provide the system's firmware framebuffer. If that device is
not known, assume that any graphics device has been initialized by
firmware.
Fixes a problem on i915 where sysfb does not release the firmware
framebuffer after the native graphics driver loaded.
