[ Upstream commit f0050a3e214aa941b78ad4caf122a735a24d81a6 ]
pm_show_wakelocks() is called to generate a string when showing attributes /sys/power/wake_(lock|unlock), but the string ends with an unwanted space that was added back by mistake by commit c9d967b2ce40 ("PM: wakeup: simplify the output logic of pm_show_wakelocks()").
Remove the unwanted space.
