[PATCH 2/5] pinctrl: mvebu: Delete an error message for a failed memory allocation in three functions

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 12 Jan 2017 16:15:34 +0100

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

WARNING: Possible unnecessary 'out of memory' message

Thus fix the affected source code places.
