Subject: [PATCH] block-LDM: One function call less in ldm_validate_tocblocks()
 after error detection

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 22 Dec 2015 22:32:07 +0100

This issue was detected by using the Coccinelle software.

Let us return directly if a memory allocation failed.
