gcc 4.3.0 prints this warning:
drivers/scsi/lpfc/lpfc_scsi.c: In function ‘lpfc_bus_reset_handler’:
drivers/scsi/lpfc/lpfc_scsi.c:1245:\
warning: ‘status’ may be used uninitialized in this function
It seems like the warning is bogus. However, this patch makes
sure status is always initialized before used.
