3.13.11.9 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Joern Engel <[email protected]> commit 8ae757d09c45102b347a1bc2867f54ffc1ab8fda upstream. In iscsi_copy_param_list() a failed iscsi_param_list memory allocation currently invokes iscsi_release_param_list() to cleanup, and will promptly trigger a NULL pointer dereference. Instead, go ahead and return for the first iscsi_copy_param_list() failure case. Found by coverity.
