[PATCH 4.14 24/50] Input: psmouse - add a newline when printing proto by sysfs

[Greg Kroah-Hartman]

From: Xiongfeng Wang <wangxiongfeng2@xxxxxxxxxx>

[ Upstream commit 4aec14de3a15cf9789a0e19c847f164776f49473 ]

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:~#
