Subject: [PATCH 5.4 82/85] Input: ati_remote2 - add missing newlines when printing module parameters

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

commit 37bd9e803daea816f2dc2c8f6dc264097eb3ebd2 upstream.

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

root@...kaller:~# cat /sys/module/ati_remote2/parameters/mode_mask
0x1froot@...kaller:~# cat /sys/module/ati_remote2/parameters/channel_mask
0xffffroot@...kaller:~#
