+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.
