From 48ba81f6fdb7580a5c474da1b14a338e1358e6ab Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 3 Feb 2014 17:40:14 +0100 Subject: [PATCH] ARM: ixp4xx: fix gpio rework Commit 098e30f6558f8 "ARM: ixp4xx: stop broadcasting the custom GPIO API" changed the internal gpio code of ixp4xx to be accessible only from common.c, but unfortunately that broke the Goramo MultiLink code, which uses this API. This tries to restore the previous state without exposing the API globally again. A better solution might be needed.
