I stumbled over a build error with COMPILE_TEST and CONFIG_OF disabled: drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe': drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node' The problem is that the newly added GPIO_TEGRA Kconfig symbol does not have a dependency on CONFIG_OF. However, there is another problem here as the driver gets enabled unconditionally whenever COMPILE_TEST is set. This fixes both problems, by making the symbol user-visible when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y. As a side-effect, it is now possible to compile-test a Tegra kernel with GPIO support disabled, which is harmless.
