Subject: [PATCH] test_power: add missing newlines when printing parameters by sysfs
Date: Fri, 4 Sep 2020 14:09:58 +0800 [thread overview]
Message-ID: <1599199798-27804-1-git-send-email-wangxiongfeng2@huawei.com> (raw)
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
onroot@syzkaller:/sys/module/test_power/parameters# cat battery_present
trueroot@syzkaller:/sys/module/test_power/parameters# cat battery_health
goodroot@syzkaller:/sys/module/test_power/parameters# cat battery_status
dischargingroot@syzkaller:/sys/module/test_power/parameters# cat battery_technology
LIONroot@syzkaller:/sys/module/test_power/parameters# cat usb_online
onroot@syzkaller:/sys/module/test_power/parameters#
