From 73deb7dc05b4cf968e506e7b18345bc65bcbc0f3 Mon Sep 17 00:00:00 2001 From: Alessandro Zummo Date: Mon, 20 Mar 2006 17:10:12 +0000 Subject: [PATCH] [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.
