Export the gpiod_request() and gpiod_free() symbols, so modular GPIO library code can make use of these functions. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- ERROR: "gpiod_free" [drivers/gpio/gpiolib-fwd.ko] undefined! ERROR: "gpiod_request" [drivers/gpio/gpiolib-fwd.ko] undefined! Alternatives: - Force gpiolib-fwd builtin, - Call gpio_{,request,free}(desc_to_gpio(...)) instead, as the legacy functions are exported, - Call gpiod_put() instead of gpiod_free(), as the former is a simple exported wrapper around the latter. Unfortunately there's no such alternative for gpiod_request(). --- drivers/gpio/gpiolib.c | 2 ++ 1 file changed, 2 insertions(+)
