[ARM] 3368/1: ixp4xx: set gpio direction in ixp4xx_config_irq
Patch from Alessandro Zummo ixp4xx_config_irq did not configure the gpio line as an input. As an added bonus, the irq2gpio array has been converted from int to char. Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
