udoo_neo: Call gpio_request()
Calling gpio_request() prior to its usage is now mandatory. This fixes the following GPIO errors: gpio@20a8000: set_dir_flags: error: gpio GPIO4_16 not reserved gpio@20a8000: set_dir_flags: error: gpio GPIO4_13 not reserved gpio@20a8000: set_dir_flags: error: gpio GPIO4_0 not reserved gpio@20a8000: get_value: error: gpio GPIO4_13 not reserved gpio@20a8000: get_value: error: gpio GPIO4_0 not reserved gpio@20a0000: set_dir_flags: error: gpio GPIO2_1 not reserved gpio@20a0000: set_value: error: gpio GPIO2_1 not reserved Fixes: 191840ae99 ("ARM: imx: udoo_neo: Enable OF_CONTROL and DM gpio/pin control") Signed-off-by: Peter Robinson <pbrobinson@gmail.com> Reviewed-by: Fabio Estevam <festevam@gmail.com>
