Subject: gpio-lpc32xx: Fix value handling of gpio_direction_output()
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.
