PM: wakeup: Delete space in the end of string shown by pm_show_wakelocks()
[ 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.
Fixes: c9d967b2ce40 ("PM: wakeup: simplify the output logic of pm_show_wakelocks()")
