[PATCH v2 09/10] OF: gpio: call of_node_put in of_get_named_gpio_flags

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Marco Felsch <m.felsch@pengutronix.de>

This aligns us with the Linux implementation. There's no functional
change though, because of_node_put is a stub in barebox (same as when
compiling kernel without CONFIG_OF_DYNAMIC enabled).

v1 -> v2:
  - reword commit message to make it clearer that patch is a no-op
    in barebox
