That's indeed not so nice...
Either we have to add it back, or do something like:
- pr_info("Detected Renesas %s %s %s\n", soc_dev_attr->family,
- soc_dev_attr->soc_id, soc_dev_attr->revision ?: "");
+ pr_info("Detected Renesas %s %s%s%s\n", soc_dev_attr->family,
+ soc_dev_attr->soc_id, soc_dev_attr->revision ? " Rev " : "",
+ soc_dev_attr->revision ?: "");
Any other options?
