It's included where there's a stable address. That's not true for GPIO controlled devices though, it's a GPIO controller plus a number. Ramming lots of information to the media entity's name field is not possible since it's just 32 bytes; for this reason we're looking to implement a better way to recognise devices in MC. But for now, we got to cope with what we have. > Regarding s/dev_info/dev_warn : Do you want to send the patch or I should do > it? Is this one merged already? If yes, sure I can. Otherwise a new version would be nice. -- Cheers, Sakari Ailus e-mail: sakari.ai...@iki.fi XMPP: sai...@retiisi.org.uk -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
