Michael Brunner 48ff5b2539 gpio: gpio-kempld: Fix get_direction return value 
commit f230e8ffc0 upstream.

This patch fixes an inverted return value of the gpio get_direction
function.

The wrong value causes the direction sysfs entry and GPIO debugfs file
to indicate incorrect GPIO direction settings. In some cases it also
prevents setting GPIO output values.

The problem is also present in all other stable kernel versions since
linux-3.12.
