Thus, we see the following warning when building blackfin image, where GPIOLIB is not required. CC arch/blackfin/kernel/bfin_gpio.o CC init/version.o In file included from arch/blackfin/include/asm/gpio.h:321, from arch/blackfin/kernel/bfin_gpio.c:15: include/asm-generic/gpio.h:298: warning: 'struct gpio_chip' declared inside parameter list include/asm-generic/gpio.h:298: warning: its scope is only this definition or declaration, which is probably not what you want include/asm-generic/gpio.h:304: warning: 'struct gpio_chip' declared inside parameter list Move pinctrl trunk into #ifdef CONFIG_GPIOLIB to fix the warning, since it appears that pinctrl gpio range support depends on GPIOLIB.
