Subject: [PATCH] [media] tw686x: add a missing newline when printing parameter 'dma_mode'

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

[root@...k-202 ~]# cat /sys/module/tw686x/parameters/dma_mode
memcpy[root@...k-202 ~]#
