wakeup sources created with the help of /sys/power/wake_lock
that are inactive at the moment, separated with spaces.

+ The /sys/power/pm_print_times file allows user space to
+ control whether the time taken by devices to suspend and
+ resume is printed. These prints are useful for hunting down
+ devices that take too long to suspend or resume.
+ Writing a "1" enables this printing while writing a "0"
+ disables it. The default value is "0". Reading from this file
+ will display the current value.
