Subject: pinctrl: core: include gpio/driver.h for struct gpio_chip
Date: Tue, 18 Aug 2026 14:34:22 -0400
Stable commit f53dd26462b8e ("pinctrl: remove pinctrl_gpio_direction_output()")
[ upstream 45d2055b0067 ] changed pinctrl_gpio_direction_input/output() to take
a struct gpio_chip * and dereference gc->base. Those functions are compiled
unconditionally, but in 6.6 core.c the struct gpio_chip definition is only
pulled in via "../gpio/gpiolib.h" under #ifdef CONFIG_GPIOLIB. Configurations
with CONFIG_PINCTRL=y and CONFIG_GPIOLIB=n (e.g. linux-yocto-tiny on x86, built
with --allnoconfig) therefore fail to build:
drivers/pinctrl/core.c: error: invalid use of undefined type 'struct gpio_chip'
Include <linux/gpio/driver.h> directly so struct gpio_chip is always a complete
type, matching how mainline core.c has included it since commit ec963d04ca865
("pinctrl: provide new GPIO-to-pinctrl glue helpers"), present in 6.12/6.18 but
not 6.6.
