Then what about: /** * Document what idx is about here. */ struct mctrl_gpios *mctrl_gpio_init_index(struct uart_port *port, unsigned int idx); static inline struct mctrl_gpios *mctrl_gpio_init(struct uart_port *port) { return mctrl_gpio_init_index(port, 0); } ? That matches how gpio and of functions use the indexed variants.
