Subject: [PATCH v2 09/12] IB/ocrdma: Delete an unnecessary variable assignment
 in ocrdma_alloc_mr()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 22 Apr 2017 15:07:41 +0200

Delete an assignment for the local variable "status" in an if branch
because the desired failure indication is already specified by a constant
error code at the end.
