OK... if you already noticed this and you are saying there are more cases, then it's better if you send a different patch. > > > if (!bridge->slot_get) { > > > - dev_warn(bridge->parent, "vme_slot_num not supported\n"); > > > + dev_warn(bridge->parent, "%s not supported\n", __func__); > > > return -EINVAL; > > > } > > > > Nothing wrong with the patch itself.

You can keep my tag, unless you are making drastic changes.

If someones acks or reviews the patches you don't need to resend just for adding the tags. There are tools doing it and maintainers take care of that. But, on the other hand, if you are going to resend anyway, for other reasons a new version, then you should add the tags yourself, otherwise they might be lost. If the new version changes considerably, then you might consider not adding any tags. Andi
