The map slot is cleared by\nqla25xx_free_req_que() (ha->req_q_map[que_id] = NULL under mq_lock)\nduring queue teardown, while the response-queue interrupt that drives\nqla2x00_error_entry() is still registered (the IRQ is released later in\nqla25xx_free_rsp_que()). If the slot is set to NULL between the two\nreads, req becomes NULL and is dereferenced.\n\nRead the slot once into req and NULL-check the local before use. mq_lock\nis a mutex and cannot be taken from interrupt context, so the single\nread plus local check is the appropriate fix for the reported NULL\ndereference."
