Yep :) ain't it nice.

No they don't, only if you use the deprecated pinctrl_add_gpio_range().
Instead, when you register your struct gpio_chip, use
gpiochip_add_pin_range() and this will use relative offsets
without relying on global GPIO numbers.
This latter call replaces pinctrl_add_gpio_range().

You're missing gpiochip_add_pin_range() ;)
