[PATCH 4.14 007/115] nvme-fc: remove double put reference if admin connect fails

From: Greg Kroah-Hartman
Date: Fri Mar 02 2018 - 05:00:13 EST


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

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

From: James Smart <jsmart2021@xxxxxxxxx>


[ Upstream commit 4596e752db02d47038cd7c965419789ab15d1985 ]

There are two put references in the failure case of initial
create_association. The first put actually frees the controller, thus the
second put references freed memory.

Remove the unnecessary 2nd put.
