It's fine with me. For information that I want in the dmesg log all the time, with no special action from the user, I personally avoid dev_dbg() because I can never figure out whether it's enabled or not. But I don't use the information from this printk, so it's completely up to you. Just let me know what you want. If you have other pending changes to this file, you can take it, or I can put it in my tree.
