3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Roland Stigge <[email protected]> commit b1268d3737c6316016026245eef276eda6b0a621 upstream. For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument (initial value of output). This patch fixes this by setting the level accordingly.
