Hi! As suggested by James Clarke earlier on this mailing list today, I have modified of_path_of_nvme such that it behaves the same way as of_path_of_scsi and just returns NULL when the call to find_obppath returns NULL.
This makes much more sense than what my previous patch did as we don't want of_path_of_nvme to return anything but NULL when not run on a system not based on Open Firmware. Thanks, Adrian
