From 638f958baeaf9d50f42cd09993f518b3a7a0f52e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 5 May 2015 18:32:20 +0200 Subject: extcon: Allow compile test of GPIO consumers if !GPIOLIB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 to fix this.
