I guess the sentence is supposed to end with "and s390"?

I would have recounted the history a bit, e.g.:

Ever since uevent support was added for AER and EEH with commit
856e1eb9bdd4 ("PCI/AER: Add uevents in AER and EEH error/resume"), it
reported PCI_ERS_RESULT_NONE as the result of ->error_detected() to
user space.

Commit 7b42d97e99d3 ("PCI/ERR: Always report current recovery status for
udev") subsequently amended AER to report the actual return value of
->error_detected().

Make the same change to EEH to align it with AER (and s390 error
recovery).
