Geert Uytterhoeven 144345a4a8 soc: bcm2835: Make !RASPBERRYPI_FIRMWARE dummies return failure ... If CONFIG_RASPBERRYPI_FIRMWARE=n: drivers/gpio/gpio-raspberrypi-exp.c: In function ‘rpi_exp_gpio_get_polarity’: drivers/gpio/gpio-raspberrypi-exp.c:71: warning: ‘get.polarity’ is used uninitialized in this function drivers/gpio/gpio-raspberrypi-exp.c: In function ‘rpi_exp_gpio_get_direction’: drivers/gpio/gpio-raspberrypi-exp.c:150: warning: ‘get.direction’ is used uninitialized in this function The dummy firmware interface functions return 0, which means success, causing subsequent code to make use of the never initialized output parameter. Fix this by making the dummy functions return an error code (-ENOSYS) instead. Note that this assumes the firmware always fills in the requested data in the CONFIG_RASPBERRYPI_FIRMWARE=y case.
