Subject: [PATCH] Input: ati_remote2 - add missing newlines when printing module parameters

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:~#
