Subject: [PATCH 5/5] [media] s2255drv: Delete an unnecessary return statement
 in five functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 20 Sep 2017 17:50:36 +0200

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

WARNING: void function return statements are not generally useful

Thus remove such a statement in the affected functions.
