Subject: [PATCH] mtd/nand/atmel: Delete an error message for a failed memory allocation in two functions

From: Markus Elfring <[email protected]>
Date: Fri, 5 Jan 2018 21:45:04 +0100

Omit an extra message for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.
