commit bbf7d0468d0da71d76cc6ec9bc8a224325d07b6b upstream.
Since commit 7b42d97e99d3 ("PCI/ERR: Always report current recovery status for udev") AER uses the result of error_detected() as parameter to pci_uevent_ers(). As pci_uevent_ers() however does not handle PCI_ERS_RESULT_NEED_RESET this results in a missing uevent for the beginning of recovery if drivers request a reset. Fix this by treating PCI_ERS_RESULT_NEED_RESET as beginning recovery.
