There is a bug in the current driver in that certain hisi_hba and port structure elements which we access when servicing the CQ interrupt do not use thread-safe accesses; these include hisi_sas_port linked-list of active slots (hisi_sas_port.entry), bitmap of currently allocated IPTT (in hisi_hba.slot_index_tags), and completion queue read pointer. As a solution, lock these elements with the hisi_hba.lock.
