[PATCH 3/4] serial: pch_uart: Delete an unnecessary return statement in two functions

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 8 Dec 2017 18:48:10 +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.
