If paint for the bike shed is still required, my preferences are: If unwinding is required, gotos are useful and the last return should be the error case. If no unwinding is required, gotos tend to be distracting and the last return should be the no error case. Trevor's new code does: if (port->serial->type->ioctl) return port->serial->type->ioctl(tty, file, cmd, arg); return -ENOIOCTLCMD; where I would have preferred: if (!port->serial->type->ioctl) return -ENOIOCTLCMD; return port->serial->type->ioctl(tty, file, cmd, arg); -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
