Subject: gpio/pch_gpio: Fix output value of pch_gpio_direction_output()
X-Git-Tag: v3.0~1046^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=88aab9341a315d81118be6b41c45e4fe32b94bc1;p=platform%2Fkernel%2Flinux-amlogic.git

gpio/pch_gpio: Fix output value of pch_gpio_direction_output()

The pch_gpio_direction_output() function was missing a write to set the
desired output value.  The function would properly set the GPIO
direction, but not the output value.  The value would have to manually
be set with a follow up call to pch_gpio_set().

Add the missing write so that pch_gpio_direction_output() sets both the
GPIO direction and value.
