    extcon: Allow compile test of GPIO consumers if !GPIOLIB · 638f958b
    Geert Uytterhoeven authored
    The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
    not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
    functionality only, can still be compiled if GPIOLIB is not enabled.
    
    Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
    appropriate.
    
    If GPIOLIB=n and asm-generic/gpio.h is not used:
    
        drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_detect_cable’:
        drivers/extcon/extcon-usb-gpio.c:63: error: implicit declaration of function ‘gpiod_get_value_cansleep’
        drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_probe’:
        drivers/extcon/extcon-usb-gpio.c:116: error: implicit declaration of function ‘devm_gpiod_get’
        drivers/extcon/extcon-usb-gpio.c:116: warning: assignment makes pointer from integer without a cast
        drivers/extcon/extcon-usb-gpio.c:122: error: implicit declaration of function ‘gpiod_set_debounce’
        drivers/extcon/extcon-usb-gpio.c:129: error: implicit declaration of function ‘gpiod_to_irq’
    
    Add the missing #include <linux/gpio/consumer.h> to fix this.
