If you add a valid reason for making this globally visible outside of drivers/[gpio|pinctrl] to the commit message I guess I can live with it because we need to think of the bigger picture: Acked-by: Linus Walleij <linus.walleij@xxxxxxxxxx> It brings to mind the now confusing "base" inside of struct gpio_chip. We all know it should go away, but since it is never used during the lifetime of the gpio_chip - or SHOULD never be used - it should rather be an argument to [devm_]gpiochip_add_data( .... int base);... Maybe something we should add to our TODO file. Yours, Linus Walleij
