Subject: [PATCH 4.14 22/22] scsi: storvsc: missing error code in storvsc_probe()

4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@...cle.com>

commit ca8dc694045e9aa248e9916e0f614deb0494cb3d upstream.

We should set the error code if fc_remote_port_add() fails.

Cc: <stable@...r.kernel.org> #v4.12+
