power: supply: test_power: add missing newlines when printing parameters by sysfs
[ Upstream commit c07fa6c163
]
When I cat some module parameters by sysfs, it displays as follows.
It's better to add a newline for easy reading.
root@syzkaller:~# cd /sys/module/test_power/parameters/
root@syzkaller:/sys/module/test_power/parameters# cat ac_online
