commit ad604f0a4c040dcb8faf44dc72db25e457c28076 upstream. 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.
