Subject: [PATCH 3.16 006/233] netxen_nic: set rcode to the return status
 from the call to netxen_issue_cmd

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Colin Ian King <colin.king@...onical.com>

commit 0fe20fafd1791f993806d417048213ec57b81045 upstream.

Currently rcode is being initialized to NX_RCODE_SUCCESS and later it
is checked to see if it is not NX_RCODE_SUCCESS which is never true. It
appears that there is an unintentional missing assignment of rcode from
the return of the call to netxen_issue_cmd() that was dropped in
an earlier fix, so add it in.

Detected by CoverityScan, CID#401900 ("Logically dead code")
