From aac7a5095b968d6c9a3e6422f31b4ad203cac9c8 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 23 Jun 2008 11:15:09 +0200 Subject: [PATCH] ppc4xx: Fix problem in gpio_config() As pointed out by Guennadi Liakhovetski (thanks), pin2 is already shifted left by one. So the additional shift is bogus.
