-Subject: [PATCH] gpio: add flags to export GPIOs when requesting
-
-commit fc3a1f04f5040255cbc086c419e4237f29f89f88 upstream.
-
-Introduce new flags to automatically export GPIOs when using the convenience
-functions gpio_request_one() or gpio_request_array(). This eases support for
-custom boards where lots of GPIOs need to be exported for customer
-applications.
