Probing xen-fbfront faults in video_is_primary_device(). The passed-in struct device is NULL since xen-fbfront doesn't assign it and the memory is kzalloc()-ed. Assign fb_info->device to avoid this.
This was exposed by the conversion of fb_is_primary_device() to video_is_primary_device() which dropped a NULL check for struct device.
