In cases when lpfc_enable_pci_dev fails, lpfc_printf_log with LOG_TRACE_EVENT set will call lpfc_dmp_dbg which uses the phba->port_list_lock. However, phba->port_list_lock does not get initialized until lpfc_setup_driver_resource_phase1. Thus, any initialization routine with LOG_TRACE_EVENT log message prior to lpfc_setup_driver_resource_phase1 will crash. Revert LOG_TRACE_EVENT back to LOG_INIT for all log messages in routines prior to lpfc_setup_driver_resource_phase1.
