Subject: tcm_qla2xxx: Fix incorrect use of __transport_register_session
From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx>
commit 75c3d0bf9caebb502e96683b2bc37f9692437e68 upstream.
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.
