Subject: [PATCH] Input: psmouse: add a newline when printing 'proto' by sysfs
Date: Mon, 20 Jul 2020 15:38:46 +0800	[thread overview]
Message-ID: <20200720073846.120724-1-wangxiongfeng2@huawei.com> (raw)

When I cat parameter 'proto' by sysfs, it displays as follows. It's
better to add a newline for easy reading.

root@syzkaller:~# cat /sys/module/psmouse/parameters/proto
autoroot@syzkaller:~#
