3.8.13.7 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Fleig <andreasfleig@xxxxxxxxx>
commit 65ab96f60621c4da8f1b4087a57b788bc4d8f27b upstream.
Fix /proc/acpi/wakeup for devices without bus or parent
This patch fixes printing the wakeup status for devices without a bus
or parent, such as laptop lid switches and sleep buttons. These devices
have an empty physical_node_list, because acpi_bind_one is never run
for them.
[rjw: White space and coding style.]
