1608 | struct gpio_chip *chip;
| ^~~~
drivers/pinctrl/core.c:1606:15: warning: unused variable 'gpio_num' [-Wunused-variable]
1607 | unsigned int gpio_num;
| ^~~~~~~~
drivers/pinctrl/core.c:1605:29: warning: unused variable 'range' [-Wunused-variable]
1606 | struct pinctrl_gpio_range *range;
| ^~~~~
