From 597c1ffffd61a15a334ce42f2a569c59f0270bcb Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
Date: Thu, 25 Feb 2010 10:25:18 +0000
Subject: Fix incorrect arguments to ioperm() call
The second argument of ioperm() is not the last port to be accessed
but rather length of the port range [port, port + len).
