It does not, you are right, and the documentation I wrote is wrong: the
packed parameter goes in and the bare argument comes out, exactly what
pinctrl_gpio_get_config() does, and what gpio-mmio relies on in patch 3.
The code is fine, the kernel-doc in driver.h and gpiolib.c and the
driver.rst paragraph are not. v5 fixes the three texts; no code change.
