Subject: fix disk_protect for linux-2.6.27
X-Git-Url: http://git.maemo.org/git/?a=commitdiff_plain;h=5445c8890aaa7168040ab7fa27c6535c43cd523d;p=monky

fix disk_protect for linux-2.6.27

The path for the sysfs attribute has changed. Also negative values show
disabled disk protect, so catch this when interpreting the file's
content.
