Subject[PATCH 2/3] Input: cyttsp4_core: Delete an unnecessary return statement in three functions
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 21 Jan 2018 21:13:21 +0100

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.
