[PATCH 7/8] [media] ttusb_dec: Add spaces for better code readability

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 13 Sep 2017 22:12:07 +0200

The script "checkpatch.pl" pointed information out like the following.

ERROR: spaces required around that '=' (ctx:VxV)

Thus fix the affected source code places.
