It avoids the repetition and it also indicates more clearly that it returns an index rather than a struct dsa_port, without needing to fire up ctags. > +{ > + return port->index; > +} > + > struct dsa_switch_driver { > struct list_head list; > const struct dsa_switch_ops *ops; > -- > 2.28.0 > Thanks, -Vladimir

Hi Vladimir Just finishing off the next version of these patches, and i looped back to check i addressed all the comments. This one i tend to disagree with. If you look at DSA drivers, a port variable is always an integer index. dp is used to refer to a dsa_port. If anything, i would suggest we rename dsa_to_port() to dsa_to_dp(), and dsa_port_from_netdev to dsa_dp_from_netdev() or maybe dsa_netdev_to_dp(). Andrew

Maybe it's just me, but I don't like the "dp" name too much, and I think all conversions of those functions sound worse with the new names. But you do have a point with the inconsistency, so I suppose you could leave the name as it is? Or maybe dsa_dlp_to_port() if you fancy that abbreviation for a devlink port?
