[PATCH v2 0/2] PCI/ERR: s390/pci: Use pci_uevent_ers() in PCI recovery
From: Niklas Schnelle

Hi All,
This series adds issuing of uevents during PCI recovery on s390. In
developing this I noticed that pci_uevent_ers() ignores
PCI_ERS_RESULT_NEED_RESET which results in
AER not generating a uevent at the beginning of recovery if drivers
request a reset as it uses the result of error_detected() as parameter
to pci_uevent_ers(). This is fixed in the first patch and relied upon by
the s390 recovery code as it also uses the result of error_detected().
Thanks,
Niklas
