[PATCH] crypto: atmel: Delete error messages for a failed memory allocation in six functions

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Thu, 15 Feb 2018 11:38:30 +0100

Omit extra messages for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.
