Subject: [PATCH 3.12 44/98] be2iscsi: set the boot_kset pointer to NULL in case of failure

From: Maurizio Lombardi <mlombard@...hat.com>

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

===============

commit 84bd64993f916bcf86270c67686ecf4cea7b8933 upstream.

In beiscsi_setup_boot_info(), the boot_kset pointer should be set to
NULL in case of failure otherwise an invalid pointer dereference may
occur later.
