From 373e9644c5f557bc8992036f9a9281e9d98aef40 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 18 May 2009 19:40:18 +0100 Subject: [ARM] S3C24XX: GPIO: Fix error returns from gpio functions Several GPIO functions have been returning -1 to indicate an error instead of returning a proper error code. Change to return -EINVAL for invalid argument(s).
