How do you think about to avoid the specification of a bit of duplicate source code here
by using conditional operator expressions?

	ret = mikrobus_pinctrl_select(port,
				      ((!board ||
					board->pin_state[MIKROBUS_PIN_PWM] == MIKROBUS_STATE_PWM)
				      ? "pwm_default"
				      : "pwm_gpio"));
