From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx> [ Upstream commit 75c3d0bf9caebb502e96683b2bc37f9692437e68 ] This patch fixes the incorrect use of __transport_register_session() in tcm_qla2xxx_check_initiator_node_acl() code, that does not perform explicit se_tpg->session_lock when accessing se_tpg->tpg_sess_list to add new se_sess nodes. Given that tcm_qla2xxx_check_initiator_node_acl() is not called with qla_hw->hardware_lock held for all accesses of ->tpg_sess_list, the code should be using transport_register_session() instead.
