Subject: pinctrl: mvebu: Delete an error message for a failed memory allocation in three functions
X-Git-Tag: v4.11-rc1~133^2~58

pinctrl: mvebu: Delete an error message for a failed memory allocation in three functions

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

WARNING: Possible unnecessary 'out of memory' message

Thus fix the affected source code places.
