Subject: [PATCH AUTOSEL 4.19 06/18] Input: psmouse - add a newline when printing 'proto' by sysfs

From: Xiongfeng Wang <wangxiongfeng2@...wei.com>

[ 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@...kaller:~# cat /sys/module/psmouse/parameters/proto
autoroot@...kaller:~#
