Subject: [PATCH 1/5] xen-netback: Delete an unnecessary assignment in
 connect_rings()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 2 Jan 2016 17:32:40 +0100

Remove the assignment for a local variable because its value is not
changed compared to the one from a previous function call.
