Subject: [PATCH 1/2] InfiniBand-iSER: One jump label less in iser_reg_sig_mr()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 27 Dec 2015 11:41:42 +0100

This issue was detected by using the Coccinelle software.

1. Let us return directly if a call of the iser_set_sig_attrs()
   function failed.

2. Delete the jump label "err" then.

3. Return zero as a constant at the end.
