Without CONFIG_GPIOLIB, some headers are not included implicitly, leading to a build failure: drivers/net/ieee802154/mcr20a.c: In function 'mcr20a_probe': drivers/net/ieee802154/mcr20a.c:1347:13: error: implicit declaration of function 'irq_get_trigger_type'; did you mean 'irq_get_irqchip_state'? [-Werror=implicit-function-declaration] This includes gpio/consumer.h and irq.h directly rather through the gpiolib header.
