Subject: [PATCH] media: uvcvideo: add a missing newline when printing parameter 'clock'

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

[root@...k-202 ~]# cat /sys/module/uvcvideo/parameters/clock
CLOCK_MONOTONIC[root@...k-202 ~]#
