 Abstract
 ========
 The Linux ACPI subsystem converts ACPI namespace objects into a Linux
-device tree under the /sys/devices/LNXSYSTEM:00 and updates it upon
+device tree under the /sys/devices/LNXSYSTM:00 and updates it upon
 receiving ACPI hotplug notification events.  For each device object
 in this hierarchy there is a corresponding symbolic link in the
 /sys/bus/acpi/devices.
