Subject: [PATCH] clk/Renesas: Delete an error message for a failed memory
 allocation in three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 25 Sep 2017 10:10:51 +0200

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

WARNING: Possible unnecessary 'out of memory' message

Thus fix affected source code places.
