Subject[PATCH/RFC v2 1/5] gpio: Export gpiod_{request,free}() to modular GPIO code
Date
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().
