I think you don't need to mention status bits here. Just use terms
"fatal" and "non-fatal" errors.

lpfc_aer_cleanup_state() requires clearing both fatal and non-fatal
uncorrectable error status. But using  pci_aer_clear_nonfatal_status()
will only clear non-fatal error status. To clear both fatal and non-fatal
error status, use pci_aer_clear_uncorrect_error_status().
