From 4ce30874f561faa15e87fcf0592eee14c26cb78b Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Wed, 20 May 2015 12:38:58 +0300 Subject: [PATCH] iscsi: Fix iscsi endpoints leak When creating a new endpoint, we look for a free id for the new endpoint. We baisically loop on possible ids and use the first id that class_find_device() returns NULL. However, we are missing a reference put when class_find_device() does find an existing device for a given id.
