Something like below?
#define RZG2L_PORT_START_OFFSET 0x10
port = RZG2L_PIN_ID_TO_PORT_pin) + RZG2L_PORT_START_OFFSET;
rzg2l_validate_gpio_pin(pctrl, *pin_data, port - RZG2L_PORT_START_OFFSET, bit)
and rename port -> port_offset in rzg2l_pinctrl_pinconf_get/set Or
would you prefer to change the RZG2L_PIN_ID_TO_PORT macro and adjust
the entire file?

Agreed.
