gpio: syscon: Fix possible NULL ptr usage
The priv->data->set can be NULL while flags contains GPIO_SYSCON_FEAT_OUT and chip->set is valid pointer. This happens in case the controller uses the default GPIO setter. Always use chip->set to access the setter to avoid possible NULL pointer dereferencing. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
